Abstract:
The cases of epithelioma cuniculatum in this report illustrate the unusual appearance and diagnostic difficulty of the lesion. Early diagnosis resulted in apparent cure with adequate local excision in some cases, whereas amputation was necessary for advanced or recurrent tumors. Distant metastasis may occur. Superficial biopsy specimens may yield inadequate tissue for proper diagnosis. Verrucous carcinoma should be considered as a diagnostic possibility in any atypical or recurrent "wart" on the sole.
