Pyogenic granulomas (PGs), also called lobular capillary hemangiomas, manifest as friable, moist or glistening, papules. PGs are a benign vascular proliferation. They often have a collarette, which is subtle in this lesion, and they bleed with minimal trauma. They are commonly seen on the gingiva during pregnancy, the umbilical area in newborns, or at sites of trauma.
Since PGs often occur during pregnancy, it’s been suggested that their development is related to hormonal changes.1 It’s also been suggested that PGs are the result of an abnormal hypertrophic healing response, as they can occur in men, infants (at the umbilical stump), and even within blood vessels.1
Although benign and painless, PGs are usually hard to ignore due to their raised appearance, tendency to bleed, and the low likelihood that they will resolve on their own. There are multiple physical treatment options available, including excision with primary closure, curettage followed by electrodessication, laser treatment, and cryosurgery. Topical therapies include timolol (a beta-blocker that has been used successfully with congenital hemangiomas), imiquimod, and trichloroacetic acid.1 These topical medications do not require any anesthetic, which may make them an appealing option for children. Unfortunately, topical medications require multiple applications over a period of 2 or more weeks.
In this case, the lesion was shaved off and sent out to pathology to rule out amelanotic melanoma. The pathology for this patient confirmed PG. Immediately following the lesion’s removal, the physician performed 2 cycles of curettage and electrodessication. Thus, the patient’s treatment was completed on the same day as her evaluation.
