Epithelioma cuniculatum plantare.

Epithelioma cuniculatum plantare is a tumor of epithelial origin occurring on the plantar aspect of the foot. It is an uncommon, locally aggressive neoplasm, not limited to this area, and in other body sites is referred to as verrucous carcinoma. The history and treatment of a patient with plantar verrucous carcinoma is presented; a survey of the literature reflects difficulty in establishing an early diagnosis. This, however, can be facilitated when the gross appearance and a history of prior surgical attempts to excise the lesion are known to the surgeon and the pathologist, and the surgical specimen ideally encompasses the deeper portions of the lesion.
