Expert Hopes to Expand Ohio Model of Melanoma Case Reporting
SAN DIEGO – Soon after Brett M. Coldiron, MD, launched his Cincinnati-based dermatology and Mohs surgery practice more than 20 years ago, he reported his first three cases of thin melanomas to the Ohio Department of Health, as mandated by state law.
“I got sent reams of paperwork to fill out that I did not understand,” Dr. Coldiron, a past president of the American College of Mohs Surgery and the American Academy of Dermatology, recalled at the annual Cutaneous Malignancy Update. “Then, I got chewed out for not reporting sooner and threatened with thousands of dollars in fines if I did not promptly report the forms in the future. It was an obnoxious experience.”
About 15 years later, while testifying at the Ohio Legislature on medical reasons to restrict the use of tanning beds, a lobbyist for the tanning bed industry told him that the melanoma rates had been stable in Ohio for the previous 5 years. “It turns out they were cherry picking certain segments of data to fit their narrative,” Dr. Coldiron said. “I was stunned and it kind of deflated me. I thought about this for a long time, and thought, ‘how do we solve this issue of reporting melanoma cases without adding work to existing staff if you’re a small practice and without spending significant amounts of money? Let’s make this easier.’ ”
In addition to reducing the use of tanning beds, proper reporting of melanoma cases is important for reasons that include efforts to increase sunscreen use and to be counted in ongoing research efforts to obtain a realistic snapshot of melanoma prevalence and incidence, he said.
Quality of melanoma case reporting relies on the Centers for Disease Control and Prevention’s National Program of Cancer Registries (NPCR), and the National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) Program, which collects data on the incidence, treatment, staging, and survival for 28% of the US population. All 50 states and US territories require melanoma to be reported to the NPCR, but while most hospital systems have reporting protocols and dedicated data registrars, private practices may not.
Also, many dermatopathology practices operate independently and do not have dedicated registrars and may not report cases. “Melanoma is unique in that it is often completely managed in outpatient settings and these melanomas may never be reported,” said Dr. Coldiron, current president of the Ohio Dermatological Foundation. “That’s the practice gap.” One study published in 2018 found that only 49% of dermatologists knew that melanoma was a reportable disease and only 34% routinely reported newly diagnosed cases to their state’s cancer registry. He characterized melanoma reporting as an unfunded mandate.
“Hospitals are doing the most of them, because they have a registrar,” he said. “Small practices have to assign someone to do this, and it can be difficult to train that person. It’s time consuming. The first time we did it, it took an hour,” but, he said, taking a 2-hour tutorial from the Ohio Department of Health helped.
He noted that there is a lack of awareness and clinicians think it’s the dermatopathologist’s job to report cases, “while the dermatopathologist thinks it’s the clinician’s job,” and many of the entry fields are not applicable to thinner melanomas.
There is also a “patchwork” of ways that state departments of health accept the information, not all electronically, he continued. For example, those in Arizona, Montana, West Virginia, Delaware, Vermont, and Maine accept paper copies only, “meaning you have to download a PDF, fill it out, and fax it back to them,” Dr. Coldiron said at the meeting, which was hosted by Scripps Cancer Center.
“We have them sign a HIPAA form and take the two-hour online tutorial,” he said. They download data that Ohio dermatologists have faxed to a dedicated secure HIPAA-compliant cloud-based fax line that Dr. Coldiron has set up, and the cases are then sent to the Ohio Department of Health.
Dr. Coldiron and colleagues have also partnered with the University of Cincinnati Clermont, which offers a National Cancer Registries Association–accredited certificate program — one of several nationwide. Students in this program are trained to become cancer registrars. “The university staff are gung-ho about it because they are looking for easy cases to train the students on. Also, the Ohio Department of Health staff are keen to help train the students and even help them find jobs or hire them after they complete the degree. Staff from the department of health and college faculty are fully engaged and supervising. It’s a win-win for all.”
According to Dr. Coldiron, in 2023, 8 Ohio dermatology practices were sending their reports to the fax line he set up and 7 more have signed up in recent months, making 15 practices to date. “It’s self-perpetuating at this point,” he said. “The Ohio Department of Health and the University of Cincinnati are invested in this program long-term.” The fax service costs Dr. Coldiron $42 per month — a small price to pay, he said, for being a clearinghouse for private Ohio dermatology practices looking for a practical way to report their melanoma cases. The model has increased melanoma reporting in Ohio by 2.8% in the last 2 years, “which doesn’t seem like that many, but if there are 6500 cases of melanoma, and you can increase reporting by a couple hundred cases, that’s a lot,” he said.
His goal is to expand this model to more states. “Dermatologists, surgical oncologists, and cancer center administrators should embrace this opportunity to make their practices a clearinghouse for their state,” he said. “This is an opportunity to improve state health, quality improvement projects, help providers, and gain recognition as a center of excellence. The increase in incidence of melanoma will lend great clout to public and legislative requests for prevention, treatment, and research dollars.”
In an interview, Hugh Greenway, MD, the head of Mohs and dermatologic surgery at Scripps Clinic in San Diego, also noted that cutaneous melanoma is significantly underreported in spite of individual state requirements. “As Dr. Coldiron reminds us, the main reason is that in many cases the pathology diagnosis and report come from the dermatologist’s/dermatopathologist’s office,” Dr. Greenway said. “With no hospital or large multispecialty laboratory involved, the reporting may be incomplete or not done. This is not the case with almost all other cancers where a hospital laboratory is involved.”
If widespread adoption of Dr. Coldiron’s model can occur, he added, “then we will have much better melanoma reporting data on which to both help our patients and specialty. He is to be applauded for producing a workable solution to the problem of underreporting.”
Dr. Coldiron reported having no relevant disclosures. Dr. Greenway reported that he conducts research for Castle Biosciences. He is also course director of the annual Cutaneous Malignancy Update.

While Rare, Periocular Melanoma May Be Slightly Increasing
SAN DIEGO — Every year, about 4000 patients in the United States are diagnosed with periocular melanoma, according to Geva Mannor, MD, MPH.
“Though rare, the incidence is thought to be slightly increasing, while the onset tends to occur in patients over age 40 years,” Dr. Mannor, an oculofacial plastic surgeon in the division of ophthalmology at Scripps Clinic, San Diego, said at the annual Cutaneous Malignancy Update. “It may be more common in males and welding is a risk factor. Pain and vision loss are late symptoms, and there are amelanotic variants. Gene expression profiling and other genetic testing can predict metastasis, especially expression of BRCA1-associated protein 1 (BAP1).”
. Extrapolating from the best available data, Dr. Mannor said that the annual incidence of choroidal melanoma in the United States is less than 2500, the annual incidence of eyelid melanoma is less than 750, and the annual incidence of conjunctival melanoma is less than 250 — much lower than for cutaneous melanomas. Put another way, the ratio between cutaneous and choroid melanoma is 80:1, the ratio between cutaneous and eyelid melanoma is 266:1, and the ratio between cutaneous and conjunctival melanoma is 800:1.
According to an article published in 2021 on the topic, risk factors for periocular melanoma include light eye color (blue/gray; relative risk, 1.75), fair skin (RR, 1.80), and inability to tan (RR, 1.64), but not blonde hair. A review of 210 patients with melanoma of the eyelid from 11 studies showed that 57% were located on the lower lid, 13% were on the upper lid (“I think because the brow protects sun exposure to the upper lid,” Dr. Mannor said), 12% were on the brow, 10% were on the lateral canthus, and 2% were on the medial canthus. In addition, 35% of the eyelid melanomas were superficial spreading cases, 31% were lentigo maligna, and 19% were nodular. The mean Breslow depth was 1.36 mm and the mortality rate was 4.9%.
Dr. Mannor said that cheek and brow melanomas can extend to the inside of the eyelid and conjunctiva. “Therefore, you want to examine the inside of upper and lower eyelids,” he said at the meeting, which was hosted by the Scripps Cancer Center. “Margin-control excision of lid melanoma is the standard treatment.”
On a related note, he said that glaucoma eye drops that contain prostaglandin F2alpha induce cutaneous and iris pigmentation with varying rates depending on the specific type of prostaglandin. “There have been case reports of these eye drops causing periocular pigmentation that masquerades as suspicious, melanoma-like skin cancer, often necessitating a skin biopsy,” he said.

Expert Shares Tips for Diagnosing, Managing Spitz Nevi
SAN DIEGO —
“For a pigmented Spitz nevus, we were taught to look for a starburst pattern, a central area of homogeneous pigment, and peripheral symmetrical streaks or pseudopods,” Dr. Piggott, an adult and pediatric dermatologist at Scripps Clinic, San Diego, said at the annual Cutaneous Malignancy Update. “For Spitz nevi without pigment, we were taught to look for symmetric dotted vessels.”
However, results from a retrospective study published in 2015 gave her pause in relying on dermoscopy alone for assessing Spitz nevi. Researchers from Italy, Japan, and Brazil studied excision specimens of 384 Spitzoid-looking lesions in patients 12 years and older. On histology, 86.7% were diagnosed as benign Spitz nevi and 13.3% were diagnosed as melanoma.
When the researchers looked at the dermoscopic images, many cases of atypical Spitz nevi were indistinguishable from the benign Spitz nevi. Now, Dr. Piggott said, “I respect the dermoscopy criteria, but I don’t rely solely on it.”
If a child presents with Spitzoid-looking lesion, biopsy is generally preferred to observation. “The traditional belief was that punch biopsy was preferable, followed by shave biopsy,” she said. “This is always on a case-by-case basis.”
However, results from a retrospective study of the records of 123 cases of biopsy-proven Spitz nevi with incomplete removal on biopsy suggests that the method of biopsy matters. The researchers found that the presence of residual lesion in the re-excision specimen was significantly higher when the initial biopsy was done by punch biopsy (90.9%) when compared with shave biopsy (48.9%) and formal excision (62.5%; P < .05).
“This suggests that shave may better than punch for the initial biopsy, but the study was limited by its retrospective design,” Dr. Piggott said at the meeting, which was hosted by Scripps Cancer Center. “Even today it remains controversial whether you should do a shave or punch biopsy.”
Parameters for diagnosing Spitzoid tumors that pathologists look for under the microscope are asymmetry, Clark’s level IV/V, lack of maturation, solid growth, nuclear pleomorphism, high nuclear-cytoplasmic ratio, and mitoses that are atypical, deep, or that exceed 6 mm2 in size.
In terms of treatment recommendations for children with biopsy-proven Spitz nevi, Dr. Piggott said that there is no consensus among pediatric dermatologists. If the biopsy comes back as a benign Spitz nevus, the most reasonable approach is observation, “especially if there is no clinical residue — no pigment on exam, no papule left over in the scar,” she said. “You also want to educate the family about the rare potential for transformation down the line. Monitor for recurrence and consider re-excision if recurrence occurs.”
If the initial Spitz nevus biopsy reveals any degree of atypia, excision is preferred. “In young children, you have to weigh the risks of anesthesia for removal,” she said. “If you’re unable to excise the lesion, close observation is recommended at 6 months or 1 year.”
Treatment for borderline atypical Spitz tumor is excision, she continued, but no outcomes data exist that document a survival benefit with sentinel lymph node (SLN) biopsy. “The decision on whether to do a SLN biopsy is usually made on a case-by-case basis,” Dr. Piggott said. “Nodal metastases from atypical Spitzoid tumors are not uncommon, but death from widespread disease is rare. If the SLN biopsy is positive, complete lymphadenectomy is associated with increased risk of morbidity and no evidence of increased survival. If lymph node disease is found, we in pediatric dermatology would consider referral to a pediatric oncologist for consideration of systemic therapy such as interferon or a newer immunotherapy.”

If the initial Spitz nevus biopsy reveals any degree of atypia, excision is preferred. “In young children, you have to weigh the risks of anesthesia for removal,” she said. “If you’re unable to excise the lesion, close observation is recommended at 6 months or 1 year.”
Treatment for borderline atypical Spitz tumor is excision, she continued, but no outcomes data exist that document a survival benefit with sentinel lymph node (SLN) biopsy. “The decision on whether to do a SLN biopsy is usually made on a case-by-case basis,” Dr. Piggott said. “Nodal metastases from atypical Spitzoid tumors are not uncommon, but death from widespread disease is rare. If the SLN biopsy is positive, complete lymphadenectomy is associated with increased risk of morbidity and no evidence of increased survival. If lymph node disease is found, we in pediatric dermatology would consider referral to a pediatric oncologist for consideration of systemic therapy such as interferon or a newer immunotherapy.”

SAN DIEGO —
“For a pigmented Spitz nevus, we were taught to look for a starburst pattern, a central area of homogeneous pigment, and peripheral symmetrical streaks or pseudopods,” Dr. Piggott, an adult and pediatric dermatologist at Scripps Clinic, San Diego, said at the annual Cutaneous Malignancy Update. “For Spitz nevi without pigment, we were taught to look for symmetric dotted vessels.”
However, results from a retrospective study published in 2015 gave her pause in relying on dermoscopy alone for assessing Spitz nevi. Researchers from Italy, Japan, and Brazil studied excision specimens of 384 Spitzoid-looking lesions in patients 12 years and older. On histology, 86.7% were diagnosed as benign Spitz nevi and 13.3% were diagnosed as melanoma.
When the researchers looked at the dermoscopic images, many cases of atypical Spitz nevi were indistinguishable from the benign Spitz nevi. Now, Dr. Piggott said, “I respect the dermoscopy criteria, but I don’t rely solely on it.”
If a child presents with Spitzoid-looking lesion, biopsy is generally preferred to observation. “The traditional belief was that punch biopsy was preferable, followed by shave biopsy,” she said. “This is always on a case-by-case basis.”
However, results from a retrospective study of the records of 123 cases of biopsy-proven Spitz nevi with incomplete removal on biopsy suggests that the method of biopsy matters. The researchers found that the presence of residual lesion in the re-excision specimen was significantly higher when the initial biopsy was done by punch biopsy (90.9%) when compared with shave biopsy (48.9%) and formal excision (62.5%; P < .05).
“This suggests that shave may better than punch for the initial biopsy, but the study was limited by its retrospective design,” Dr. Piggott said at the meeting, which was hosted by Scripps Cancer Center. “Even today it remains controversial whether you should do a shave or punch biopsy.”
Parameters for diagnosing Spitzoid tumors that pathologists look for under the microscope are asymmetry, Clark’s level IV/V, lack of maturation, solid growth, nuclear pleomorphism, high nuclear-cytoplasmic ratio, and mitoses that are atypical, deep, or that exceed 6 mm2 in size.
In terms of treatment recommendations for children with biopsy-proven Spitz nevi, Dr. Piggott said that there is no consensus among pediatric dermatologists. If the biopsy comes back as a benign Spitz nevus, the most reasonable approach is observation, “especially if there is no clinical residue — no pigment on exam, no papule left over in the scar,” she said. “You also want to educate the family about the rare potential for transformation down the line.

More Than 100K New Cutaneous Melanoma Diagnoses Expected in 2024
SAN DIEGO — According to data from the
“The incidence of melanoma seems to have continued to go up since the early 1990s,” David E. Kent, MD, a dermatologist at Skin Care Physicians of Georgia, Macon, said at the annual Cutaneous Malignancy Update. “The death rates have been flat and may have slightly decreased.”
In 2024, the ACS estimates that about 100,640 new melanomas will be diagnosed in the United States (59,170 in men and 41,470 in women), and about 8,290 people are expected to die of melanoma (5,430 men and 2,860 women). Meanwhile, the lifetime risk of melanoma is about 3% (1 in 33) for Whites, 0.1% (1 in 1,000) for Blacks, and 0.5% (1 in 200) for Hispanics. In 2019, there were an estimated 1.4 million people in the United States living with cutaneous melanoma, and the overall 5-year survival is 93.7%.
Epidemiologic studies show an increase in melanoma incidence, primarily among White populations. “This is believed to be due to sun exposure, changes in recreational behaviors, and tanning bed exposures,” said Dr. Kent, who holds a faculty position in the department of dermatology at the Medical College of Georgia, Augusta. Increased surveillance and diagnosis also play a role. In the medical literature, annual increases in melanoma incidence vary from 3%-7% per year, “which means that the rate is doubling every 10-20 years,” he said, noting that annual melanoma costs are approximately $3.3 billion.
While incidence rates are lower in non-White, non-Hispanic populations, poor outcomes are disproportionately higher in persons of color, according to a 2023 paper. Black individuals present at diagnosis with more advanced stage disease and are 1.5 times more likely to die from melanoma, he said, while Hispanics are 2.4 times more likely to present with stage III disease and 3.6 times more likely to have distant metastases. Persons of color also have higher rates of mucosal, acral lentiginous, and subungual melanoma.
Risk Factors
Known genetic risk factors for melanoma include having skin types I and II, particularly those with light hair, light eyes, and freckling, and those with a family history have a twofold increased risk. Also, up to 40% of genetic cases are from inherited mutations in CDKN2A, CDK4, BAP1 and MCR1. Other genetic-related risk factors include the number and size of nevi, having atypical nevus syndrome, DNA repair defects, large congenital nevi, and a personal history of melanoma.
Dr. Kent said that genetic testing for melanoma is warranted for individuals who meet criteria for the “rule of 3s.” He defined this as three primary melanomas in an individual, or three cases of melanoma in first- or second-degree relatives, or two cases of melanoma and one pancreatic cancer or astrocytoma in first or second-degree relatives, or one case of melanoma and two of pancreatic cancer/astrocytoma in first- or second-degree relatives.
The main environmental risk factor for melanoma is exposure to ultraviolet radiation. Individuals can track their UV exposure with a variety of wearable devices and apps, including SunSense One Digital UV Tracker, the SunSense App, the UV Index Widget, the SunSmart Global UV App, the SunKnown UV light photometer, and the EPA’s UV Index Mobile App. Other environment-related risk factors include having a high socioeconomic status (SES), being immunosuppressed, as well as exposure to heavy metals, insecticides, or hormones; and ones distance from the equator.
In a study published in 2023, researchers investigated the risk factors associated with first and second primary melanomas in 38,845 patients who were followed in Australia between 2011 and 2018. During a median follow-up of 7.4 years, 1212 patients (3.1%) had a single primary melanoma diagnosis and 245 (0.6%) had a secondary primary melanoma diagnosis. The researchers found that second melanomas were more likely than first melanomas to be in situ; for invasive tumors, second melanomas were more likely to be thin (defined as 1 mm or less) than first melanomas. In addition, having many self-reported moles at age 21 years was more strongly associated with second melanomas compared with first melanomas (hazard ratio, 6.36 vs 3.46, respectively; P = .01), as was having a high genetic predisposition (HR, 3.28 vs. 2.06; P = .03). Second melanomas were also more strongly associated with a history of multiple skin cancer excisions (HR, 2.63 vs 1.86; P = .05).
Dr. Kent noted that while sunscreen use protects against melanoma, a National Ambulatory Medical Care Survey in 2014 found that internists and pediatricians mentioned sunscreen at fewer than 0.1% of visits — even those with patients who have a diagnosis of skin disease. “Physicians need to do better,” he said at the meeting, which was hosted by the Scripps Cancer Center. “We as dermatologists have work to do to help educate them.”
