Verrucous Carcinoma Arising in Ulcerative Lichen Planus of the Soles

Abstract
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.
