Abstract
- Dermatofibrosarcoma protuberans (DFSP) is an uncommon soft tissue neoplasm which typically originates in the dermis and spreads into the subcutaneous layer and muscle. We report an extremely rare case of a perianal DFSP mimicking mucinous adenocarcinoma arising from anorectal fistula in a 59-year-old woman. In case of a perianal mass, which is connected by a stalk to the anus and shows heterogeneous enhancement without related regional lymphadenopathy, DFSP should be included in the differential diagnosis.
