Microscopically controlled surgery (Mohs' chemosurgery) for treatment of verrucous squamous cell carcinoma of the foot (epithelioma cuniculatum).

In two cases of epithelioma cuniculatum, a rather rare form of verrucous carcinoma of the plantar surface of the foot, the lesions were excised by means of microscopically controlled surgery (Mohs' chemosurgery) with successful results, both clinically and cosmetically. Although the tumor is generally slow-growing and often mistaken for a plantar wart, it can cause extensive local destruction. Metastasis has been reported and may be related to anaplastic transformation caused by radiotherapy. In certain cases, amputation may possibly be avoided through the use of microscopically controlled surgery.
