Carcinoma cuniculatum (verrucous carcinoma) of the foot

A patient with carcinoma cuniculatum of the foot, an uncommon tumor, is presented. This tumor, also reported as verrucous carcinoma and epithelioma cuniculatum, is a low-grade, squamous cell carcinoma of the skin that rarely metastasizes. The highly keratinizing lesion has a locally destructive course, but with treatment by excision, it has a low recurrence rate.
