title: Pedunculated Nodules as a Variant of Dermatofibrosarcoma Protuberans.
abstract: Dermatofibrosarcoma protuberans (DFSP) is a rare disease of dermal fibroblastic origin that accounts for less than 5% of all soft tissue sarcomas in adults. DFSP grows slowly and is an asymptomatic lesion at the initial diagnosis. Herein, we report a case of multiple pedunculated nodules as a variant of DFSP. A 47-year-old man presented with a 7-month history of multiple well-circumscribed, firm, pedunculated nodules on the inguinal area. Histopathologic examination results showed densely packed uniform spindle cells with a storiform and cartwheel pattern, and positivity for CD34. Wide excision and skin graft were performed and at the 6-month follow-up, there was no evidence of recurrence or metastasis.
