Subungual Fibrokeratoma. A two-case report

Abstract

Subungual fibrokeratoma is a benign fibroepithelial tumor and topographic variant of acquired digital fibrokeratomas. It is identified as a digitiform or filiform neoformation located on the fingers and, less frequently, on the toes; being predominant on middle-aged male adults. Although its etiology is unknown, trauma to the lesion may be considered as a contributing factor. Definitive diagnosis is histopathological, and complete surgical excision is the first-line treatment. Two subungual digital fibrokeratoma cases are described.
