Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous tumor with a tendency towards local recurrence. A 26-year-old woman presented with a 3 × 2 cm raised, purple-hued lesion on her left breast. Excisional biopsy identified the lesion as a DFSP. She underwent two additional operations to achieve widely clear margins. Operative excision is the primary treatment of dermatofibrosarcoma protuberans of the breast.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
