Pigmented Dermatofibrosarcoma Protuberans: A Case Report and Review of Literature

Abstract

Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous sarcoma. Bednar tumor (BT) or pigmented DFSP is a rarely reported variant of it. The only differentiating feature between them is the presence of melanocytes on histopathological examination. We report a case of a 23-year-old female who presented with a recurrent lump in the right thigh that on histopathological evaluation was diagnosed as BT. Less than hundred cases of BT have been recorded to date, with only five cases originating from the thigh. Clinicopathological features of recurrent cases have been compared as local recurrence is less commonly reported.
