Attendees of the 2024 American Academy of Dermatology annual meeting in San Diego, California, were eager to delve into the latest trends and advancements in dermatology and dermatologic surgery. This article provides a few key takeaways for residents from a range of engaging sessions, with an emphasis on procedural dermatology and physician health and well-being.

Practical Applications of Surgical Enhancements

In an informative session dedicated to dermatologic surgeons and their patients, “Simple Tricks and Practical Tips to Optimize the Surgical Experience for You and Your Patients,” attendees learned practical tips for enhancing the surgical experience. The discussion spanned various aspects of surgery, from managing preoperative anxiety with anxiolytics such as midazolam to the strategic use of skin hooks for delicate tissue manipulation. Midazolam is fast acting and its use is tailored to patient factors such as weight, hepatic function, and prior use. An innovative anxiety management algorithm combining “talkesethesia” with other methods such as anodynes and benzodiazepines underscored the importance of a calm patient in successful surgical outcomes. Talkesthesia involves engaging patients in soothing and distracting conversation throughout the procedure. This technique can include discussing nonmedical topics of interest with the patient—such as their hobbies, family, or favorite movies—to divert their attention from the surgical process and reduce anxiety. By creating a friendly and reassuring atmosphere, talkesthesia helps to establish trust between the patient and the medical team, ultimately contributing to a more relaxed and cooperative patient.¹

The utility of skin hooks also was discussed, with an emphasis on their role in ensuring gentle tissue handling. The modified buried vertical mattress technique was discussed for its added benefits in wound approximation and strength. Emphasis was placed on the importance of maintaining a clear surgical field by electrocautery to ensure optimal visibility.

Focusing on the treatment of skin cancer, curettage alone was touted as a viable alternative to electrodesiccation and curettage, especially in reducing postoperative hypopigmentation while maintaining high cure rates. This method was shown to be effective in treating basal cell carcinoma and well-differentiated squamous cell carcinoma.^2,3

Suturing techniques such as pulley, purse-string, and buried sutures offer efficiencies in time, cost, and improved healing in high-tension areas. These methods can contribute to postsurgical aesthetic and functional outcomes. Additionally, Dr. Desiree Ratner shared her tips for painless local anesthesia techniques, emphasizing the importance of patient comfort through methods such as slow injection and buffering of lidocaine. The next time you give a local anesthetic, try this technique to minimize pain: using a 30-gauge needle, hold the syringe with the bevel up, insert only the bevel into the skin (needle tip goes into the papillary dermis), and numb superficially around the periphery using as little volume as possible. Keep pressure slow and steady without moving the needle, then insert the needle only in previously anesthetized areas, numbing deeply only after the entire periphery has been anesthetized.

The session concluded with the recommendation to provide patients with a goody bag containing postoperative supplies. This thoughtful gesture not only enhances patient satisfaction but also addresses the practical aspect of postsurgery care, offering an inexpensive yet impactful way to ensure patients have the necessary supplies for their recovery.

Take-Home Point—This session distilled essential surgical enhancements into practical applications, emphasizing the importance of anxiety management, delicate tissue handling, innovative suturing techniques, and thoughtful patient care postsurgery. The overarching message highlighted the synergy between technical skill and patient-centric approaches in optimizing surgical outcomes, underscoring the significance of attention to detail in every aspect of patient care, from preoperative preparation to postoperative recovery.

Optimizing Safety and Ergonomics in Surgical Practices

Understanding the dynamics of surgical plume is crucial to safety in the operating room. The carcinogenic risk associated with surgical smoke is not trivial: exposure to the plume generated by monopolar electrocautery in a single day can be equivalent to smoking approximately 30 cigarettes, and a surgeon’s lifetime cancer risk from polycyclic aromatic hydrocarbons exposure is alarmingly high.⁴ To mitigate these risks, several strategies were recommended, including using lower-energy settings, choosing indirect or bipolar cautery, and ensuring efficient room ventilation with HEPA (high-efficiency particulate absorbing) filters to turn over air frequently. Additionally, employing the use of smoke evacuators and suction devices with proper filters can reduce particulate matter in the operating room.

The importance of the surgeon’s posture during procedures also was emphasized for ergonomic benefits and to minimize fatigue. Maintaining a neutral stance with the core and glutes engaged, standing on the balls of the feet, and aligning the table height to keep the hands at the lower chest level were recommended; this not only helps in reducing strain but also in maintaining precision during surgical tasks.

The surgeons on the panel also highlighted the novel use of hydrocolloid dressings with tattoo lasers, electrodesiccation and curettage for treating rhinophyma, and purse-string closure for chest defects as evolving practices to enhance outcomes and safety.

The session offered valuable insights into suturing techniques, advocating for the use of deep sutures—­ideally Monocryl (Ethicon US, LLC)—for superficial closures and fast-absorbing gut sutures for patients who are not expected to return for suture removal. Keith LeBlanc Jr, MD, shared one of his favorite tricks for suturing fragile, sun-damaged skin on the forearm in elderly patients: apply adhesive skin closures aligned parallel to the suture line, then suture through them for extra support. This can help ensure a more secure closure.

In situations when no deep sutures are required, such as on the hair-bearing scalp, large bites through the galea using monofilament nonabsorbable sutures for up to 14 days or staples can offer favorable closures and enhanced hemostasis. Tranexamic acid has emerged as a versatile hemostatic agent—available in multiple forms ranging from direct injection to topical applications—and is cost-effective, enhancing its accessibility in various surgical settings.

A high proportion of patients are taken aback by the length of the scar following removal of what they perceive as a small skin cancer. Leslie Storey, MD, cleverly recommended using the back of a glove to mark surgical ­planning, giving the patient a visual guide for anticipating the size of the excision. This is a simple yet effective approach to enhance patient understanding and informed consent. 

Lastly, the notion that “patients remember you if you don’t cause them pain” resonated deeply, underlining the importance of gentle techniques such as pinching the suture rather than pushing the wound edges together and asking assistants to maintain tension without obstructing the field. In the words of Seth Matarasso, MD: “If you pain ‘em, you won’t retain ‘em!”

Take-Home Point—The take-home message from the session was a comprehensive approach to surgical excellence that aligns technical proficiency with a strong emphasis on safety, patient comfort, and operative efficiency. Surgeons were advised to adopt practices that reduce the risks associated with surgical plume, maintain ergonomic discipline, and apply innovative suturing techniques to enhance patient outcomes. Compassionate patient care, innovative use of materials and methods, and a commitment to continual learning and adaptation of new evidence-based practices are paramount for the modern surgeon.

Approaches for Facial Reconstruction

The intricacies of multisubunit facial reconstruction were explored in a session that blended the pursuit of aesthetic harmony with functional restoration, “Simplifying the Complex: Reconstructing Multisubunit Defects.” The session began with an introduction to flap design principles, emphasizing the importance of thorough defect analysis and the strategic design of flaps. A key objective within this framework is the integration of the flap within existing cosmetic subunits to avoid unwanted effects such as unintended eyebrow elevation.

The concept of tissue reservoirs was discussed,focusing on regions such as the glabella as potential sources for skin recruitment. This then transitioned into a nuanced discussion on incision planning, underscoring the significance of aligning incision lines with relaxed skin tension lines to enhance healing and minimize scarring.

The topic of delayed reconstruction also was introduced as a deliberate tactic for high-risk tumor management. This approach allows for an in-depth pathologic examination and provides patients with more time for psychological adjustment, which may be particularly important for those with complex medical histories or those who require staged surgical interventions.

In a thorough examination of flap design techniques, the session highlighted the bilobed transposition flap as a versatile choice for nasal reconstruction, particularly apt for the distal third of the nose due to its design that harnesses skin from nonadjacent areas. Accompanying this was an exploration of Zitelli modifications, which enhance the bilobed flap by reducing issues such as pincushioning through a moderated rotation angle and the strategic incorporation of a Burow triangle.

Finally, the interpolated paranasal flap was discussed. This technique is designed to reduce the risk for cheek asymmetry and is suitable for patients with generous donor sites; however, this method requires diligent evaluation to avoid complications such as external nasal valve collapse.

Take-Home Point—This session highlighted approaches in facial reconstruction, emphasizing the necessity of strategic flap design and meticulous incision planning to maintain aesthetic harmony and functional integrity.

Strategies for Improving Physician Well-Being

Evidence-based recommendations to support physicians’ well-being are crucial as the health care system becomes increasingly demanding. Instead of focusing on aspects of the health care system that frequently are outside of physicians’ control, the session “A Realistic and Evidence-Based Roadmap for Thriving in Life and Career” discussed many practical, self-empowering tools and strategies to lead a happier and healthier life—both personally and professionally.

The speakers cautioned against the concept of an “unlimited ceiling” for achieving a certain goal, where an unlimited amount of time and energy is allowed to be dedicated to a given task over a period of time. They highlighted the potential consequences of this approach, such as stress, dissatisfaction, and ultimately burnout. The speakers explored the concept of well-being as a continuous journey rather than a destination, emphasizing that it is not the opposite of burnout. To promote well-being, the speakers advocated for utilizing concepts rooted in positive psychology to empower the individual rather than longing for a different environment. They hypothesized that changing one’s life can be accomplished by changing one’s mind, independent of the environment.

The roadmap for physician well-being, as presented by clinical psychologist Amy MacDonald, PsyD, commenced with urging the audience to introspect on situations and experiences, categorizing them into “feel good” and “feel bad” buckets. For every feel-good event, Dr. MacDonald proposed 5 mental exercises for optimized well-being: (1) control/increase: evaluate whether one can control or increase the frequency of the event; (2) consider: reflect on why this event feels good and explore other aspects to gain any additional joy from the event; (3) share: recognize that some feel goods are more joyous when shared; (4) value: connect the feel-good experiences with personal core values, as research shows value affirmations can buffer neuroendocrine and psychological stress responses; and (5) savor: deliberately relish each small or notable feel-good moment.

Similarly, after labeling an event as a feel-bad experience, Dr. MacDonald encouraged the audience to go through mental exercises to strengthen their well-being journey; however, before proceeding, she highlighted the importance of arming ourselves with self-compassion. The 5 mental exercises to address feel bads include (1) solve: assess whether we have control over the situation and attempt to make changes if possible; (2) reframe: explore new perspectives and assess assumptions without minimizing the situation; (3) connect: embrace the positive impact of safe human connections on our stress response; (4) reflect: search curiously using a compassionate lens for any existing patterns of reactions; and (5) accept and pivot: allow thoughts and feelings to exist and pivot to values-based engagement without waiting for the environment to change. Consistently seeking and appreciating feel goods while addressing rather than suppressing the feel bads can lead to joyful satisfaction and overall well-being.

Additional pearls for optimizing physician well-being included accurately labeling emotions rather than lumping them into an overarching theme (eg, stressed), avoiding comparisons with others, choosing courage over comfort, celebrating vulnerability, and embracing the ability to say no to prioritize engagements aligned with one’s purpose and values. Additional resources were shared for further reading, including Emotional Agility by Susan David, Daring Greatly and Rising Strong by Brené Brown, and Self-Compassion by Kristin Neff.

Take-Home Point—This lecture highlighted key strategies for physicians to improve their well-being, emphasizing self-empowerment and practical tools over external circumstances. It distinguished between productive and destructive influences on satisfaction, and emphasized decision-making aligned with personal values. The concept of well-being as a journey, not a destination, was central, encouraging positive psychology and self-reflection to enhance fulfillment. By focusing on amplifying feel-good experiences and addressing feel-bad experiences with resilience, the lecture advocated for internal over external change, offering a pathway to a balanced and satisfying professional and personal life for physicians.

To promote well-being, the speakers advocated for utilizing concepts rooted in positive psychology to empower the individual rather than longing for a different environment. They hypothesized that changing one’s life can be accomplished by changing one’s mind, independent of the environment.

The roadmap for physician well-being, as presented by clinical psychologist Amy MacDonald, PsyD, commenced with urging the audience to introspect on situations and experiences, categorizing them into “feel good” and “feel bad” buckets. For every feel-good event, Dr. MacDonald proposed 5 mental exercises for optimized well-being: (1) control/increase: evaluate whether one can control or increase the frequency of the event; (2) consider: reflect on why this event feels good and explore other aspects to gain any additional joy from the event; (3) share: recognize that some feel goods are more joyous when shared; (4) value: connect the feel-good experiences with personal core values, as research shows value affirmations can buffer neuroendocrine and psychological stress responses; and (5) savor: deliberately relish each small or notable feel-good moment.

Similarly, after labeling an event as a feel-bad experience, Dr. MacDonald encouraged the audience to go through mental exercises to strengthen their well-being journey; however, before proceeding, she highlighted the importance of arming ourselves with self-compassion. The 5 mental exercises to address feel bads include (1) solve: assess whether we have control over the situation and attempt to make changes if possible; (2) reframe: explore new perspectives and assess assumptions without minimizing the situation; (3) connect: embrace the positive impact of safe human connections on our stress response; (4) reflect: search curiously using a compassionate lens for any existing patterns of reactions; and (5) accept and pivot: allow thoughts and feelings to exist and pivot to values-based engagement without waiting for the environment to change. Consistently seeking and appreciating feel goods while addressing rather than suppressing the feel bads can lead to joyful satisfaction and overall well-being.

Additional pearls for optimizing physician well-being included accurately labeling emotions rather than lumping them into an overarching theme (eg, stressed), avoiding comparisons with others, choosing courage over comfort, celebrating vulnerability, and embracing the ability to say no to prioritize engagements aligned with one’s purpose and values. Additional resources were shared for further reading, including Emotional Agility by Susan David, Daring Greatly and Rising Strong by Brené Brown, and Self-Compassion by Kristin Neff.

Take-Home Point—This lecture highlighted key strategies for physicians to improve their well-being, emphasizing self-empowerment and practical tools over external circumstances. It distinguished between productive and destructive influences on satisfaction, and emphasized decision-making aligned with personal values. The concept of well-being as a journey, not a destination, was central, encouraging positive psychology and self-reflection to enhance fulfillment. By focusing on amplifying feel-good experiences and addressing feel-bad experiences with resilience, the lecture advocated for internal over external change, offering a pathway to a balanced and satisfying professional and personal life for physicians.

Final Thoughts

The recent American Academy of Dermatology meeting offered valuable insights and practical pearls to enhance surgical practices and promote physician well-being, in addition to a wide range of topics beyond what is mentioned in this article. From optimizing surgical techniques to prioritizing patient care and safety, the sessions underscored the importance of continuous learning and adaptation in the ever-evolving field of dermatology. As we reflect on the lessons learned and the camaraderie shared during this gathering, let us carry forward these teachings to improve patient outcomes, foster innovation, and cultivate resilience in our pursuit of excellence. Together, we can continue to push the boundaries of dermatologic care while nurturing our own well-being and that of our colleagues, ensuring a brighter future for both patients and practitioners alike.

Basal cell carcinoma (BCC) of the ear may have aggressive histologic subtypes and a greater propensity for subclinical spread than BCC in other anatomic locations. In this retrospective analysis, we evaluated recurrence rates of BCC of the ear in 102 patients who underwent treatment with Mohs micrographic surgery (MMS) or radiation therapy (RT) at a single institution between January 2017 and December 2019. Data on patient demographics, tumor characteristics, treatment modality, and recurrence rates were collected from medical records. Recurrence rates were assessed over a mean follow-up time of 2.8 years. Although MMS is the gold standard for treatment of BCC of the ear, RT may be a suitable alternative for nonsurgical candidates.

Basal cell carcinoma (BCC) of the ear may have aggressive histologic subtypes and a greater propensity for subclinical spread than BCC in other anatomic locations. Given that these aggressive histologic subtypes—defined as morpheaform, basosquamous, sclerosing, infiltrative, or micronodular in any portion of the tumor—have been reported as independent predictors of recurrence,^1,2 BCC of the ear may be more likely to recur.

Mohs micrographic surgery (MMS) is the gold standard for the treatment of BCC of the ear. For nonsurgical candidates—those with high bleeding risk, low life expectancy, or other medical or social factors—definitive radiation therapy (RT) may be an option. Our study sought to examine recurrence rates in patients with BCC of the ear treated with MMS vs RT.

Methods

A retrospective review of patients undergoing treatment of BCC of the ear at Bighorn Mohs Surgery and Dermatology Center (San Diego, California) between January 2017 and December 2019 was conducted. A total of 507 medical records were reviewed, and 102 patients were included in the study. Inclusion criteria consisted of biopsy-confirmed BCC of the ear that was treated with MMS, RT, or both. Data on patient demographics, tumor characteristics, treatment modality, and recurrence rates were collected from medical records. This retrospective review of medical records was exempt from institutional review board approval, as it did not involve direct human research subjects, solely entailing a retrospective examination of existing data.

Results

Of the 102 patients included, 82 were male and 20 were female, with an average age of 71 years. All patients were White with the exception of 1 patient whose race was unknown. Two patients were immunocompromised. The helix was identified as the most frequently involved site on the ear (Table). Most of the tumors (56/102) exhibited aggressive histologic subtypes; 36 tumors had nonaggressive histology, and 10 had no subtype listed. Two of the BCCs demonstrated perineural invasion on biopsy. Mohs micrographic surgery was used to treat 96 BCCs, definitive RT was used to treat 5 BCCs (all of which occurred in nonsurgical candidates), and MMS and adjuvant RT were used in 1 patient given multifocal perineural involvement. All 5 patients treated with definitive RT received electron beam radiation therapy; the total dose ranged from 5100 to 6000 cGy divided into 17 to 24 fractions. The final MMS defects ranged from 6 to 55 mm in size. The average follow-up time was 2.8 years. One of the BCCs on the helix that was treated with MMS recurred after 1.3 years. The overall recurrence rate was 0.98%. None of the patients treated with definitive RT experienced recurrence after the mean follow-up time of 2.8 years.

Comment

Basal cell carcinoma is the most commonly diagnosed cancer in the United States, with approximately 2 million new cases each year.¹ Treatment modalities for localized BCC include MMS, surgical excision, electrodesiccation and curettage, topical and intralesional medications, laser therapy, and RT. For high-risk BCCs, MMS is associated with the lowest recurrence rates⁴ and remains the gold standard for treatment. For patients with contraindications to surgery, definitive RT is an alternative treatment for high-risk BCC.¹

Definitive RT can be employed for patients who are poor surgical candidates or when surgery would result in substantial morbidity, impaired function, and/or poor cosmesis.³ Radiation therapy for skin cancers of the ear commonly is administered using high-energy electrons that produce double-strand breaks in the DNA of malignant cells, leading to cell death.⁴ Disadvantages of RT compared to MMS include a longer treatment course (3 to 6 weeks), possible minimal long-term cosmetic sequelae (eg, color or texture mismatch), lack of pathologic confirmation of margin control, and small risk for secondary malignancy in the treatment field over 2 to 3 decades. For patients with incurable or metastatic disease, palliative RT can provide local control and/or symptomatic relief to improve quality of life.⁴ Adjuvant RT may be indicated if there is substantial perineural involvement or positive margins after MMS when margins are unable to be achieved or in patients who may not tolerate prolonged or extensive surgical procedures.³

Basal cell carcinoma of the ear is considered a high-risk anatomic location independent of other prognostic factors. Basal cell carcinomas of the ear have a higher propensity for more aggressive histologic subtypes and subclinical spread.⁵ Our study demonstrated a higher proportion of aggressive histologic subtypes (56/102 [54.9%]) compared with nonaggressive subtypes (36/102 [35.3%]). There was 1 recurrence of a nodular, sclerosing, and infiltrative BCC on the helix treated with MMS after 1.3 years.

Limitations of our study include that it was conducted at a single institution with a homogenous study population and with relatively short follow-up.

Conclusion

Our study further validates the well-known utility of MMS for the treatment of BCC of the ears. Definitive RT is a suitable alternative for patients who are not surgical candidates. Adjuvant RT may be considered for substantial perineural involvement or positive margins after MMS.³

Hidradenitis suppurativa (HS) is a chronic inflammatory, androgen gland disorder characterized by recurrent rupture of the hair follicles with a vigorous inflammatory response. This response results in abscess formation and development of draining sinus tracts and hypertrophic fibrous scars.^1,2 Pain, discomfort, and odorous discharge from the recalcitrant lesions have a profound impact on patient quality of life.^3,4

The morbidity and disease burden associated with HS are particularly underestimated, as patients frequently report debilitating pain that often is overlooked.^5,6 Additionally, the quality and intensity of perceived pain are compounded by frequently associated depression and anxiety.^7-9 Pain has been reported by patients with HS to be the highest cause of morbidity, despite the disfiguring nature of the disease and its associated psychosocial distress.^7,10 Nonetheless, HS lacks an accepted pain management algorithm similar to those that have been developed for the treatment of other acute or chronic pain disorders, such as back pain and sickle cell disease.^4,11-13

Given the lack of formal studies regarding pain management in patients with HS, clinicians are limited to general pain guidelines, expert opinion, small trials, and patient preference.³ Furthermore, effective pain management in HS necessitates the treatment of both chronic pain affecting daily function and acute pain present during disease flares, surgical interventions, and dressing changes.³ The result is a wide array of strategies used for HS-associated pain.^3,4

Epidemiology and Pathophysiology

Hidradenitis suppurativa historically has been an overlooked and underdiagnosed disease, which limits epidemiology data.⁵ Current estimates are that HS affects approximately 1% of the general population; however, prevalence rates range from 0.03% to 4.1%.^14-16

The exact etiology of HS remains unclear, but it is thought that genetic factors, immune dysregulation, and environmental/behavioral influences all contribute to its pathophysiology.^1,17 Up to 40% of patients with HS report a positive family history of the disease.^18-20 Hidradenitis suppurativa has been associated with other inflammatory disease states, such as inflammatory bowel disease, spondyloarthropathies, and pyoderma gangrenosum.^16,21,22

It is thought that HS is the result of some defect in keratin clearance that leads to follicular hyperkeratinization and occlusion.¹ Resultant rupture of pilosebaceous units and spillage of contents (including keratin and bacteria) into the surrounding dermis triggers a vigorous inflammatory response. Sinus tracts and fistulas become the targets of bacterial colonization, biofilm formation, and secondary infection. The result is suppuration and extension of the lesions as well as sustained chronic inflammation.^23,24

Although the etiology of HS is complex, several modifiable risk factors for the disease have been identified, most prominently cigarette smoking and obesity. Approximately 70% of patients with HS smoke cigarettes.^2,15,25,26 Obesity has a well-known association with HS, and it is possible that weight reduction lowers disease severity.^27-30

Clinical Presentation and Diagnosis

Establishing a diagnosis of HS necessitates recognition of disease morphology, topography, and chronicity. Hidradenitis suppurativa most commonly occurs in the axillae, inguinal and anogenital region, perineal region, and inframammary region.^5,31 A typical history involves a prolonged disease course with recurrent lesions and intermittent periods of improvement or remission. Primary lesions are deep, inflamed, painful, and sterile. Ultimately, these lesions rupture and track subcutaneously.^15,25 Intercommunicating sinus tracts form from multiple recurrent nodules in close proximity and may ultimately lead to fibrotic scarring and local architectural distortion.³² The Hurley staging system helps to guide treatment interventions based on disease severity. Approach to pain management is discussed below.

Pain Management in HS: General Principles

Pain management is complex for clinicians, as there are limited studies from which to draw treatment recommendations. Incomplete understanding of the etiology and pathophysiology of the disease contributes to the lack of established management guidelines.

A PubMed search of articles indexed for MEDLINE using the terms hidradenitis, suppurativa, pain, and management revealed 61 different results dating back to 1980, 52 of which had been published in the last 5 years. When the word acute was added to the search, there were only 6 results identified. These results clearly reflect a better understanding of HS-mediated pain as well as clinical unmet needs and evolving strategies in pain management therapeutics. However, many of these studies reflect therapies focused on the mediation or modulation of HS pathogenesis rather than potential pain management therapies.

In addition, the heterogenous nature of the pain experience in HS poses a challenge for clinicians. Patients may experience multiple pain types concurrently, including inflammatory, noninflammatory, nociceptive, neuropathic, and ischemic, as well as pain related to arthritis.^3,33,34 Pain perception is further complicated by the observation that patients with HS have high rates of psychiatric comorbidities such as depression and anxiety, both of which profoundly alter perception of both the strength and quality of pain.^7,8,22,35 A suggested algorithm for treatment of pain in HS is described in the eTable.³⁶

CT108005281_eTable.JPG

Chronicity is a hallmark of HS. Patients experience a prolonged disease course involving acute painful exacerbations superimposed on chronic pain that affects all aspects of daily life. Changes in self-perception, daily living activities, mood state, physical functioning, and physical comfort frequently are reported to have a major impact on quality of life.^1,3,37

In 2018, Thorlacius et al³⁸ created a multistakeholder consensus on a core outcome set of domains detailing what to measure in clinical trials for HS. The authors hoped that the routine adoption of these core domains would promote the collection of consistent and relevant information, bolster the strength of evidence synthesis, and minimize the risk for outcome reporting bias among studies.³⁸ It is important to ascertain the patient’s description of his/her pain to distinguish between stimulus-dependent nociceptive pain vs spontaneous neuropathic pain.^3,7,10 The most common pain descriptors used by patients are “shooting,” “itchy,” “blinding,” “cutting,” and “exhausting.”¹⁰ In addition to obtaining descriptive factors, it is important for the clinician to obtain information on the timing of the pain, whether or not the pain is relieved with spontaneous or surgical drainage, and if the patient is experiencing chronic background pain secondary to scarring or skin contraction.³ With the routine utilization of a consistent set of core domains, advances in our understanding of the different elements of HS pain, and increased provider awareness of the disease, the future of pain management in patients with HS seems promising.

Acute and Perioperative Pain Management

Acute Pain Management—The pain in HS can range from mild to excruciating.^3,7 The difference between acute and chronic pain in this condition may be hard to delineate, as patients may have intense acute flares on top of a baseline level of chronic pain.^3,7,14 These factors, in combination with various pain types of differing etiologies, make the treatment of HS-associated pain a therapeutic challenge.

The first-line treatments for acute pain in HS are oral acetaminophen, oral nonsteroidal anti-inflammatory drugs (NSAIDs), and topical analgesics.³ These treatment modalities are especially helpful for nociceptive pain, which often is described as having an aching or tender quality.³ Topical treatment for acute pain episodes includes diclofenac gel and liposomal lidocaine cream.³⁹ Topical lidocaine in particular has the benefit of being rapid acting, and its effect can last 1 to 2 hours. Ketamine has been anecdotally used as a topical treatment. Treatment options for neuropathic pain include topical amitriptyline, gabapentin, and pregabalin.³⁹ Dressings and ice packs may be used in cases of mild acute pain, depending on patient preference.³

First-line therapies may not provide adequate pain control in many patients.^3,40,41 Should the first-line treatments fail, oral opiates can be considered as a treatment option, especially if the patient has a history of recurrent pain unresponsive to milder methods of pain control.^3,40,41 However, prudence should be exercised, as patients with HS have a higher risk for opioid abuse, and referral to a pain specialist is advisable.⁴⁰ Generally, use of opioids should be limited to the smallest period of time possible.^40,41 Codeine can be used as a first opioid option, with hydromorphone available as an alternative.⁴¹

Pain caused by inflamed abscesses and nodules can be treated with either intralesional corticosteroids or incision and drainage. Intralesional triamcinolone has been found to cause substantial pain relief within 1 day of injection in patients with HS.^3,42

Prompt discussion about the remitting course of HS will prepare patients for flares. Although the therapies discussed here aim to reduce the clinical severity and inflammation associated with HS, achieving pain-free remission can be challenging. Barriers to developing a long-term treatment regimen include intolerable side effects or simply nonresponsive disease.^36,43

Management of Perioperative Pain—Medical treatment of HS often yields only transient or mild results. Hurley stage II or III lesions typically require surgical removal of affected tissues.^32,44-46 Surgery may dramatically reduce the primary disease burden and provide substantial pain relief.^3,4,44 Complete resection of the affected tissue by wide excision is the most common surgical procedure used.^46-48 However, various tissue-sparing techniques, such as skin-tissue-sparing excision with electrosurgical peeling, also have been utilized. Tissue-sparing surgical techniques may lead to shorter healing times and less postoperative pain.⁴⁸

There currently is little guidance available on the perioperative management of pain as it relates to surgical procedures for HS. The pain experienced from surgery varies based on the area and location of affected tissue; extent of disease; surgical technique used; and whether primary closure, closure by secondary intention, or skin grafting is utilized.^47,49 Medical treatment aimed at reducing inflammation prior to surgical intervention may improve postoperative pain and complications.

The use of general vs local anesthesia during surgery depends on the extent of the disease and the amount of tissue being removed; however, the use of local anesthesia has been associated with a higher recurrence of disease, possibly owing to less aggressive tissue removal.⁵⁰ Intraoperatively, the injection of 0.5% bupivacaine around the wound edges may lead to less postoperative pain.^3,48 Postoperative pain usually is managed with acetaminophen and NSAIDs.⁴⁸ In cases of severe postoperative pain, short- and long-acting opioid oxycodone preparations may be used. The combination of diclofenac and tramadol also has been used postoperatively.³ Patients who do not undergo extensive surgery often can leave the hospital the same day.

Effective strategies for mitigating HS-associated pain must address the chronic pain component of the disease. Long-term management involves lifestyle modifications and pharmacologic agents.

Chronic Pain Management

Although HS is not a curable disease, there are treatments available to minimize symptoms. Long-term management of HS is essential to minimize the effects of chronic pain and physical scarring associated with inflammation.³¹ In one study from the French Society of Dermatology, pain reported by patients with HS was directly associated with severity and duration of disease, emotional symptoms, and reduced functionality.⁵¹ For these reasons, many treatments for HS target reducing clinical severity and achieving remission, often defined as more than 6 months without any recurrence of lesions.⁵² In addition to lifestyle management, therapies available to manage HS include topical and systemic medications as well as procedures such as surgical excision.^36,43,52,53

Lifestyle Modifications

Regardless of the severity of HS, all patients may benefit from basic education on the pathogenesis of the disease.³⁶ The associations with smoking and obesity have been well documented, and treatment of these comorbid conditions is indicated.^36,43,52 For example, in relation to obesity, the use of metformin is very well tolerated and seems to positively impact HS symptoms.⁴³ Several studies have suggested that weight reduction lowers disease severity.^28-30 Patients should be counseled on the importance of smoking cessation and weight loss.

Finally, the emotional impact of HS is not to be discounted, both the physical and social discomfort as well as the chronicity of the disease and frustration with treatment.⁵¹ Chronic pain has been associated with increased rates of depression, and 43% of patients with HS specifically have been diagnosed with major depressive disorder.⁷ For these reasons, clinician guidance, social support, and websites can improve patient understanding of the disease, adherence to treatment, and comorbid anxiety and depression.⁵²

Topical Therapy

Topical therapy generally is limited to mild disease and is geared at decreasing inflammation or superimposed infection.^36,52 Some of the earliest therapies used were topical antibiotics.⁴³ Topical clindamycin has been shown to be as effective as oral tetracyclines in reducing the number of abscesses, but neither treatment substantially reduces pain associated with smaller nodules.⁵⁴ Intralesional corticosteroids such as triamcinolone acetonide have been shown to decrease both patient-reported pain and physician-assessed severity within 1 to 7 days.⁴² Routine injection, however, is not a feasible means of long-term treatment both because of inconvenience and the potential adverse effects of corticosteroids.^36,52 Both topical clindamycin and intralesional steroids are helpful in reducing inflammation prior to planned surgical intervention.^36,52,53

Newer topical therapies include resorcinol peels and combination antimicrobials, such as 2% triclosan and oral zinc gluconate.^52,53 Data surrounding the use of resorcinol in mild to moderate HS are promising and have shown decreased severity of both new and long-standing nodules. Fifteen-percent resorcinol peels are helpful tools that allow for self-administration by patients during exacerbations to decrease pain and flare duration.^55,56 In a 2016 clinical trial, a combination of oral zinc gluconate with topical triclosan was shown to reduce flare-ups and nodules in mild HS.⁵⁷ Oral zinc alone may have anti-inflammatory properties and generally is well tolerated.^43,53 Topical therapies have a role in reducing HS-associated pain but often are limited to milder disease.

Systemic Agents

Several therapeutic options exist for the treatment of HS; however, a detailed description of their mechanisms and efficacies is beyond the scope of this review, which is focused on pain. Briefly, these systemic agents include antibiotics, retinoids, corticosteroids, antiandrogens, and biologics.^43,52,53

Treatment with antibiotics such as tetracyclines or a combination of clindamycin plus rifampin has been shown to produce complete remission in 60% to 80% of users; however, this treatment requires more than 6 months of antibiotic therapy, which can be difficult to tolerate.^52,53,58 Relapse is common after antibiotic cessation.^2,43,52 Antibiotics have demonstrated efficacy during acute flares and in reducing inflammatory activity prior to surgery.⁵²

Retinoids have been utilized in the treatment of HS because of their action on sebaceous glands and hair follicles.^43,53 Acitretin has been shown to be the most effective oral retinoid available in the United States.⁴³ Unfortunately, many of the studies investigating the use of retinoids for treatment of HS are limited by small sample size.^36,43,52

Because HS is predominantly an inflammatory condition, immunosuppressants have been adapted to manage patients when antibiotics and topicals have failed. Systemic steroids rarely are used for long-term therapy because of the severe side effects and are preferred only for acute management.^36,52 Cyclosporine and dapsone have demonstrated efficacy in treating moderate to severe HS, whereas methotrexate and colchicine have shown little efficacy.⁵² Both cyclosporine and dapsone are difficult to tolerate, require laboratory monitoring, and lead to only conservative improvement rather than remission in most patients.⁴³

Immune dysregulation in HS involves elevated levels of proinflammatory cytokines such as tumor necrosis factor α (TNF-α), which is a key mediator of inflammation and a stimulator of other inflammatory cytokines.^59,60 The first approved biologic treatment of HS was adalimumab, a TNF-α inhibitor, which showed a 50% reduction in total abscess and inflammatory nodule count in 60% of patients with moderate to severe HS.^61-63 Of course, TNF-α inhibitor therapy is not without risks, specifically those of infection.^43,53,61,62 Maintenance therapy may be required if patients relapse.^53,61

Various interleukin inhibitors also have emerged as potential therapies for HS, such as ustekinumab and anakinra.^36,64 Both have been subject to numerous small case trials that have reported improvements in clinical severity and pain; however, both drugs were associated with a fair number of nonresponders.^36,64,65

Surgical Procedures

Although HS lesions may regress on their own in a matter of weeks, surgical drainage allows an acute alleviation of the severe burning pain associated with HS flares.^36,52,53 Because of improved understanding of the disease pathophysiology, recent therapies targeting the hair follicle have been developed and have shown promising results. These therapies include laser- and light-based procedures. Long-pulsed Nd:YAG laser therapy reduces the number of hair follicles and sebaceous glands and has been effective for Hurley stage I or II disease.^{36,43,52,53,66} Photodynamic therapy offers a less-invasive option compared to surgery and laser therapy.^52,53,66 Both Nd:YAG and CO₂ laser therapy offer low recurrence rates (<30%) due to destruction of the apocrine unit.^43,53 Photodynamic therapy for mild disease offers a less-invasive option compared to surgery and laser therapy.⁵³ There is a need for larger randomized controlled trials involving laser, light, and CO₂ therapies.⁶⁶

Conclusion

Hidradenitis suppurativa is a debilitating condition with an underestimated disease burden. Although the pathophysiology of the disease is not completely understood, it is evident that pain is a major cause of morbidity. Patients experience a multitude of acute and chronic pain types: inflammatory, noninflammatory, nociceptive, neuropathic, and ischemic. Pain perception and quality of life are further impacted by psychiatric conditions such as depression and anxiety, both of which are common comorbidities in patients with HS. Several pharmacologic agents have been used to treat HS-associated pain with mixed results. First-line treatment of acute pain episodes includes oral acetaminophen, NSAIDs, and topical analgesics. Management of chronic pain includes utilization of topical agents, systemic agents, and biologics, as well as addressing lifestyle (eg, obesity, smoking status) and psychiatric comorbidities. Although these therapies have roles in HS pain management, the most effective pain remedies developed thus far are limited to surgery and TNF-α inhibitors. Optimization of pain control in patients with HS requires multidisciplinary collaboration among dermatologists, pain specialists, psychiatrists, and other members of the health care team. Further large-scale studies are needed to create an evidence-based treatment algorithm for the management of pain in HS.

Hidradenitis suppurativa (HS) is a chronic inflammatory, androgen gland disorder characterized by recurrent rupture of the hair follicles with a vigorous inflammatory response. This response results in abscess formation and development of draining sinus tracts and hypertrophic fibrous scars.^1,2 Pain, discomfort, and odorous discharge from the recalcitrant lesions have a profound impact on patient quality of life.^3,4

The morbidity and disease burden associated with HS are particularly underestimated, as patients frequently report debilitating pain that often is overlooked.^5,6 Additionally, the quality and intensity of perceived pain are compounded by frequently associated depression and anxiety.^7-9 Pain has been reported by patients with HS to be the highest cause of morbidity, despite the disfiguring nature of the disease and its associated psychosocial distress.^7,10 Nonetheless, HS lacks an accepted pain management algorithm similar to those that have been developed for the treatment of other acute or chronic pain disorders, such as back pain and sickle cell disease.^4,11-13

Given the lack of formal studies regarding pain management in patients with HS, clinicians are limited to general pain guidelines, expert opinion, small trials, and patient preference.³ Furthermore, effective pain management in HS necessitates the treatment of both chronic pain affecting daily function and acute pain present during disease flares, surgical interventions, and dressing changes.³ The result is a wide array of strategies used for HS-associated pain.^3,4

Epidemiology and Pathophysiology

Hidradenitis suppurativa historically has been an overlooked and underdiagnosed disease, which limits epidemiology data.⁵ Current estimates are that HS affects approximately 1% of the general population; however, prevalence rates range from 0.03% to 4.1%.^14-16

The exact etiology of HS remains unclear, but it is thought that genetic factors, immune dysregulation, and environmental/behavioral influences all contribute to its pathophysiology.^1,17 Up to 40% of patients with HS report a positive family history of the disease.^18-20 Hidradenitis suppurativa has been associated with other inflammatory disease states, such as inflammatory bowel disease, spondyloarthropathies, and pyoderma gangrenosum.^16,21,22

It is thought that HS is the result of some defect in keratin clearance that leads to follicular hyperkeratinization and occlusion.¹ Resultant rupture of pilosebaceous units and spillage of contents (including keratin and bacteria) into the surrounding dermis triggers a vigorous inflammatory response. Sinus tracts and fistulas become the targets of bacterial colonization, biofilm formation, and secondary infection. The result is suppuration and extension of the lesions as well as sustained chronic inflammation.^23,24

Although the etiology of HS is complex, several modifiable risk factors for the disease have been identified, most prominently cigarette smoking and obesity. Approximately 70% of patients with HS smoke cigarettes.^2,15,25,26 Obesity has a well-known association with HS, and it is possible that weight reduction lowers disease severity.^27-30

Clinical Presentation and Diagnosis

Establishing a diagnosis of HS necessitates recognition of disease morphology, topography, and chronicity. Hidradenitis suppurativa most commonly occurs in the axillae, inguinal and anogenital region, perineal region, and inframammary region.^5,31 A typical history involves a prolonged disease course with recurrent lesions and intermittent periods of improvement or remission. Primary lesions are deep, inflamed, painful, and sterile. Ultimately, these lesions rupture and track subcutaneously.^15,25 Intercommunicating sinus tracts form from multiple recurrent nodules in close proximity and may ultimately lead to fibrotic scarring and local architectural distortion.³² The Hurley staging system helps to guide treatment interventions based on disease severity. Approach to pain management is discussed below.

Pain Management in HS: General Principles

Pain management is complex for clinicians, as there are limited studies from which to draw treatment recommendations. Incomplete understanding of the etiology and pathophysiology of the disease contributes to the lack of established management guidelines.

A PubMed search of articles indexed for MEDLINE using the terms hidradenitis, suppurativa, pain, and management revealed 61 different results dating back to 1980, 52 of which had been published in the last 5 years. When the word acute was added to the search, there were only 6 results identified. These results clearly reflect a better understanding of HS-mediated pain as well as clinical unmet needs and evolving strategies in pain management therapeutics. However, many of these studies reflect therapies focused on the mediation or modulation of HS pathogenesis rather than potential pain management therapies.

In addition, the heterogenous nature of the pain experience in HS poses a challenge for clinicians. Patients may experience multiple pain types concurrently, including inflammatory, noninflammatory, nociceptive, neuropathic, and ischemic, as well as pain related to arthritis.^3,33,34 Pain perception is further complicated by the observation that patients with HS have high rates of psychiatric comorbidities such as depression and anxiety, both of which profoundly alter perception of both the strength and quality of pain.^7,8,22,35 A suggested algorithm for treatment of pain in HS is described in the eTable.³⁶

CT108005281_eTable.JPG

Chronicity is a hallmark of HS. Patients experience a prolonged disease course involving acute painful exacerbations superimposed on chronic pain that affects all aspects of daily life. Changes in self-perception, daily living activities, mood state, physical functioning, and physical comfort frequently are reported to have a major impact on quality of life.^1,3,37

In 2018, Thorlacius et al³⁸ created a multistakeholder consensus on a core outcome set of domains detailing what to measure in clinical trials for HS. The authors hoped that the routine adoption of these core domains would promote the collection of consistent and relevant information, bolster the strength of evidence synthesis, and minimize the risk for outcome reporting bias among studies.³⁸ It is important to ascertain the patient’s description of his/her pain to distinguish between stimulus-dependent nociceptive pain vs spontaneous neuropathic pain.^3,7,10 The most common pain descriptors used by patients are “shooting,” “itchy,” “blinding,” “cutting,” and “exhausting.”¹⁰ In addition to obtaining descriptive factors, it is important for the clinician to obtain information on the timing of the pain, whether or not the pain is relieved with spontaneous or surgical drainage, and if the patient is experiencing chronic background pain secondary to scarring or skin contraction.³ With the routine utilization of a consistent set of core domains, advances in our understanding of the different elements of HS pain, and increased provider awareness of the disease, the future of pain management in patients with HS seems promising.

Acute and Perioperative Pain Management

Acute Pain Management—The pain in HS can range from mild to excruciating.^3,7 The difference between acute and chronic pain in this condition may be hard to delineate, as patients may have intense acute flares on top of a baseline level of chronic pain.^3,7,14 These factors, in combination with various pain types of differing etiologies, make the treatment of HS-associated pain a therapeutic challenge.

The first-line treatments for acute pain in HS are oral acetaminophen, oral nonsteroidal anti-inflammatory drugs (NSAIDs), and topical analgesics.³ These treatment modalities are especially helpful for nociceptive pain, which often is described as having an aching or tender quality.³ Topical treatment for acute pain episodes includes diclofenac gel and liposomal lidocaine cream.³⁹ Topical lidocaine in particular has the benefit of being rapid acting, and its effect can last 1 to 2 hours. Ketamine has been anecdotally used as a topical treatment. Treatment options for neuropathic pain include topical amitriptyline, gabapentin, and pregabalin.³⁹ Dressings and ice packs may be used in cases of mild acute pain, depending on patient preference.³

First-line therapies may not provide adequate pain control in many patients.^3,40,41 Should the first-line treatments fail, oral opiates can be considered as a treatment option, especially if the patient has a history of recurrent pain unresponsive to milder methods of pain control.^3,40,41 However, prudence should be exercised, as patients with HS have a higher risk for opioid abuse, and referral to a pain specialist is advisable.⁴⁰ Generally, use of opioids should be limited to the smallest period of time possible.^40,41 Codeine can be used as a first opioid option, with hydromorphone available as an alternative.⁴¹

Pain caused by inflamed abscesses and nodules can be treated with either intralesional corticosteroids or incision and drainage. Intralesional triamcinolone has been found to cause substantial pain relief within 1 day of injection in patients with HS.^3,42

Prompt discussion about the remitting course of HS will prepare patients for flares. Although the therapies discussed here aim to reduce the clinical severity and inflammation associated with HS, achieving pain-free remission can be challenging. Barriers to developing a long-term treatment regimen include intolerable side effects or simply nonresponsive disease.^36,43

Management of Perioperative Pain—Medical treatment of HS often yields only transient or mild results. Hurley stage II or III lesions typically require surgical removal of affected tissues.^32,44-46 Surgery may dramatically reduce the primary disease burden and provide substantial pain relief.^3,4,44 Complete resection of the affected tissue by wide excision is the most common surgical procedure used.^46-48 However, various tissue-sparing techniques, such as skin-tissue-sparing excision with electrosurgical peeling, also have been utilized. Tissue-sparing surgical techniques may lead to shorter healing times and less postoperative pain.⁴⁸

There currently is little guidance available on the perioperative management of pain as it relates to surgical procedures for HS. The pain experienced from surgery varies based on the area and location of affected tissue; extent of disease; surgical technique used; and whether primary closure, closure by secondary intention, or skin grafting is utilized.^47,49 Medical treatment aimed at reducing inflammation prior to surgical intervention may improve postoperative pain and complications.

The use of general vs local anesthesia during surgery depends on the extent of the disease and the amount of tissue being removed; however, the use of local anesthesia has been associated with a higher recurrence of disease, possibly owing to less aggressive tissue removal.⁵⁰ Intraoperatively, the injection of 0.5% bupivacaine around the wound edges may lead to less postoperative pain.^3,48 Postoperative pain usually is managed with acetaminophen and NSAIDs.⁴⁸ In cases of severe postoperative pain, short- and long-acting opioid oxycodone preparations may be used. The combination of diclofenac and tramadol also has been used postoperatively.³ Patients who do not undergo extensive surgery often can leave the hospital the same day.

Effective strategies for mitigating HS-associated pain must address the chronic pain component of the disease. Long-term management involves lifestyle modifications and pharmacologic agents.

Chronic Pain Management

Although HS is not a curable disease, there are treatments available to minimize symptoms. Long-term management of HS is essential to minimize the effects of chronic pain and physical scarring associated with inflammation.³¹ In one study from the French Society of Dermatology, pain reported by patients with HS was directly associated with severity and duration of disease, emotional symptoms, and reduced functionality.⁵¹ For these reasons, many treatments for HS target reducing clinical severity and achieving remission, often defined as more than 6 months without any recurrence of lesions.⁵² In addition to lifestyle management, therapies available to manage HS include topical and systemic medications as well as procedures such as surgical excision.^36,43,52,53

Lifestyle Modifications

Regardless of the severity of HS, all patients may benefit from basic education on the pathogenesis of the disease.³⁶ The associations with smoking and obesity have been well documented, and treatment of these comorbid conditions is indicated.^36,43,52 For example, in relation to obesity, the use of metformin is very well tolerated and seems to positively impact HS symptoms.⁴³ Several studies have suggested that weight reduction lowers disease severity.^28-30 Patients should be counseled on the importance of smoking cessation and weight loss.

Finally, the emotional impact of HS is not to be discounted, both the physical and social discomfort as well as the chronicity of the disease and frustration with treatment.⁵¹ Chronic pain has been associated with increased rates of depression, and 43% of patients with HS specifically have been diagnosed with major depressive disorder.⁷ For these reasons, clinician guidance, social support, and websites can improve patient understanding of the disease, adherence to treatment, and comorbid anxiety and depression.⁵²

Topical Therapy

Topical therapy generally is limited to mild disease and is geared at decreasing inflammation or superimposed infection.^36,52 Some of the earliest therapies used were topical antibiotics.⁴³ Topical clindamycin has been shown to be as effective as oral tetracyclines in reducing the number of abscesses, but neither treatment substantially reduces pain associated with smaller nodules.⁵⁴ Intralesional corticosteroids such as triamcinolone acetonide have been shown to decrease both patient-reported pain and physician-assessed severity within 1 to 7 days.⁴² Routine injection, however, is not a feasible means of long-term treatment both because of inconvenience and the potential adverse effects of corticosteroids.^36,52 Both topical clindamycin and intralesional steroids are helpful in reducing inflammation prior to planned surgical intervention.^36,52,53

Newer topical therapies include resorcinol peels and combination antimicrobials, such as 2% triclosan and oral zinc gluconate.^52,53 Data surrounding the use of resorcinol in mild to moderate HS are promising and have shown decreased severity of both new and long-standing nodules. Fifteen-percent resorcinol peels are helpful tools that allow for self-administration by patients during exacerbations to decrease pain and flare duration.^55,56 In a 2016 clinical trial, a combination of oral zinc gluconate with topical triclosan was shown to reduce flare-ups and nodules in mild HS.⁵⁷ Oral zinc alone may have anti-inflammatory properties and generally is well tolerated.^43,53 Topical therapies have a role in reducing HS-associated pain but often are limited to milder disease.

Systemic Agents

Several therapeutic options exist for the treatment of HS; however, a detailed description of their mechanisms and efficacies is beyond the scope of this review, which is focused on pain. Briefly, these systemic agents include antibiotics, retinoids, corticosteroids, antiandrogens, and biologics.^43,52,53

Treatment with antibiotics such as tetracyclines or a combination of clindamycin plus rifampin has been shown to produce complete remission in 60% to 80% of users; however, this treatment requires more than 6 months of antibiotic therapy, which can be difficult to tolerate.^52,53,58 Relapse is common after antibiotic cessation.^2,43,52 Antibiotics have demonstrated efficacy during acute flares and in reducing inflammatory activity prior to surgery.⁵²

Various interleukin inhibitors also have emerged as potential therapies for HS, such as ustekinumab and anakinra.^36,64 Both have been subject to numerous small case trials that have reported improvements in clinical severity and pain; however, both drugs were associated with a fair number of nonresponders.^36,64,65

Topical therapy generally is limited to mild disease and is geared at decreasing inflammation or superimposed infection.^36,52 Some of the earliest therapies used were topical antibiotics.⁴³ Topical clindamycin has been shown to be as effective as oral tetracyclines in reducing the number of abscesses, but neither treatment substantially reduces pain associated with smaller nodules.⁵⁴ Intralesional corticosteroids such as triamcinolone acetonide have been shown to decrease both patient-reported pain and physician-assessed severity within 1 to 7 days.⁴² Routine injection, however, is not a feasible means of long-term treatment both because of inconvenience and the potential adverse effects of corticosteroids.^36,52 Both topical clindamycin and intralesional steroids are helpful in reducing inflammation prior to planned surgical intervention.^36,52,53

Newer topical therapies include resorcinol peels and combination antimicrobials, such as 2% triclosan and oral zinc gluconate.^52,53 Data surrounding the use of resorcinol in mild to moderate HS are promising and have shown decreased severity of both new and long-standing nodules. Fifteen-percent resorcinol peels are helpful tools that allow for self-administration by patients during exacerbations to decrease pain and flare duration.^55,56 In a 2016 clinical trial, a combination of oral zinc gluconate with topical triclosan was shown to reduce flare-ups and nodules in mild HS.⁵⁷ Oral zinc alone may have anti-inflammatory properties and generally is well tolerated.^43,53 Topical therapies have a role in reducing HS-associated pain but often are limited to milder disease.

Systemic Agents

Several therapeutic options exist for the treatment of HS; however, a detailed description of their mechanisms and efficacies is beyond the scope of this review, which is focused on pain. Briefly, these systemic agents include antibiotics, retinoids, corticosteroids, antiandrogens, and biologics.^43,52,53

Treatment with antibiotics such as tetracyclines or a combination of clindamycin plus rifampin has been shown to produce complete remission in 60% to 80% of users; however, this treatment requires more than 6 months of antibiotic therapy, which can be difficult to tolerate.^52,53,58 Relapse is common after antibiotic cessation.^2,43,52 Antibiotics have demonstrated efficacy during acute flares and in reducing inflammatory activity prior to surgery.⁵²

Retinoids have been utilized in the treatment of HS because of their action on sebaceous glands and hair follicles.^43,53 Acitretin has been shown to be the most effective oral retinoid available in the United States.⁴³ Unfortunately, many of the studies investigating the use of retinoids for treatment of HS are limited by small sample size.^36,43,52

Because HS is predominantly an inflammatory condition, immunosuppressants have been adapted to manage patients when antibiotics and topicals have failed. Systemic steroids rarely are used for long-term therapy because of the severe side effects and are preferred only for acute management.^36,52 Cyclosporine and dapsone have demonstrated efficacy in treating moderate to severe HS, whereas methotrexate and colchicine have shown little efficacy.⁵² Both cyclosporine and dapsone are difficult to tolerate, require laboratory monitoring, and lead to only conservative improvement rather than remission in most patients.⁴³

Immune dysregulation in HS involves elevated levels of proinflammatory cytokines such as tumor necrosis factor α (TNF-α), which is a key mediator of inflammation and a stimulator of other inflammatory cytokines.^59,60 The first approved biologic treatment of HS was adalimumab, a TNF-α inhibitor, which showed a 50% reduction in total abscess and inflammatory nodule count in 60% of patients with moderate to severe HS.^61-63 Of course, TNF-α inhibitor therapy is not without risks, specifically those of infection.^43,53,61,62 Maintenance therapy may be required if patients relapse.^53,61

Various interleukin inhibitors also have emerged as potential therapies for HS, such as ustekinumab and anakinra.^36,64 Both have been subject to numerous small case trials that have reported improvements in clinical severity and pain; however, both drugs were associated with a fair number of nonresponders.^36,64,65

Surgical Procedures

Although HS lesions may regress on their own in a matter of weeks, surgical drainage allows an acute alleviation of the severe burning pain associated with HS flares.^36,52,53 Because of improved understanding of the disease pathophysiology, recent therapies targeting the hair follicle have been developed and have shown promising results. These therapies include laser- and light-based procedures. Long-pulsed Nd:YAG laser therapy reduces the number of hair follicles and sebaceous glands and has been effective for Hurley stage I or II disease.^{36,43,52,53,66} Photodynamic therapy offers a less-invasive option compared to surgery and laser therapy.^52,53,66 Both Nd:YAG and CO₂ laser therapy offer low recurrence rates (<30%) due to destruction of the apocrine unit.^43,53 Photodynamic therapy for mild disease offers a less-invasive option compared to surgery and laser therapy.⁵³ There is a need for larger randomized controlled trials involving laser, light, and CO₂ therapies.⁶⁶

Conclusion

Hidradenitis suppurativa is a debilitating condition with an underestimated disease burden. Although the pathophysiology of the disease is not completely understood, it is evident that pain is a major cause of morbidity. Patients experience a multitude of acute and chronic pain types: inflammatory, noninflammatory, nociceptive, neuropathic, and ischemic. Pain perception and quality of life are further impacted by psychiatric conditions such as depression and anxiety, both of which are common comorbidities in patients with HS. Several pharmacologic agents have been used to treat HS-associated pain with mixed results. First-line treatment of acute pain episodes includes oral acetaminophen, NSAIDs, and topical analgesics. Management of chronic pain includes utilization of topical agents, systemic agents, and biologics, as well as addressing lifestyle (eg, obesity, smoking status) and psychiatric comorbidities. Although these therapies have roles in HS pain management, the most effective pain remedies developed thus far are limited to surgery and TNF-α inhibitors. Optimization of pain control in patients with HS requires multidisciplinary collaboration among dermatologists, pain specialists, psychiatrists, and other members of the health care team. Further large-scale studies are needed to create an evidence-based treatment algorithm for the management of pain in HS.
