Carcinoma Cuniculatum of the Lower Leg: A Case Report and Proposed Diagnostic Criteria

Abstract: Carcinoma cuniculatum is an infrequent variant of squamous cell carcinoma described for the first time by Ian Aird in 1954. Since then, multiple reports of cutaneous carcinoma cuniculatum have been published at various sites, including palms, soles, buttocks, and lower legs, but most of them did not match to original description. In the current study, we report a unique case of a 69-year-old woman with carcinoma cuniculatum arising in the calf. Moreover, we update the histopathological criteria of cutaneous carcinoma cuniculatum by combining the literature descriptions and the experiences from the current case.
