Carcinoma Cuniculatum Masquerading as Wart

Abstract

Carcinoma cuniculatum is a rare, slow growing tumour which is commonly mistaken for warts or corn especially when it presents on the sole. Although it rarely metastasizes, it may cause local invasion affecting the underlying tissue and bone. Early identification provides good prognosis as it can be managed with localized resection. We present a case of carcinoma cuniculatum which was misdiagnosed and treated as a common wart for two years until the diagnosis was confirmed by histopathology. By the time of diagnosis, the lesion had involved the underlying bone and patient required amputation. Carcinoma cuniculatum is rare and easily confused with common warts in the early stages hence, it is important to create awareness to identify and differentiate these two conditions.
