Verrucous carcinoma is a low-grade squamous cell carcinoma. Chronic inflammation is an important factor in its pathogenesis. This is the first case of plantar verrucous carcinoma arising in a lesion of ulcerative lichen planus. This paper also lends further support to the successful use of Mohs micrographic surgical technique as the treatment of choice for verrucous carcinoma.
A 15-year-old white male had an extensive skin eruption that had been present since age 2 years. Physical examination revealed flesh-colored, rough-textured papules surrounded by faint erythema. These lesions were present diffusely over the upper trunk, arms, thighs, face, ears, and neck. Evaluation of four immediate family members revealed a similarly affected brother and father. A biopsy of the papules showed the presence of a mid-dermal epithelial cyst containing numerous vellus hairs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
