Abstract
Dermatofibrosarcoma protuberans (DFSP) is a rare sarcoma of soft tissue representing about 1% of all tumors. In addition, DFSP occurs commonly on the trunk and extremities, and only a few cases of DFSP have been observed on the breast. In men, only 11 cases, including this case, have been reported. In this article, we present a case of left breast DFSP that occurred in a 44-year-old man. The physical examination revealed a left breast tender mass, which invaded the skin. The tumor was staged as T4b N0 M0. Mammography and sonography showed a suspect mass of the left breast. The biopsy and immunochemistry permitted the diagnosis of DFSP of the left breast. The patient had a left mammectomy, with free margins. He presents no evident sign of recurrence 7 months later.

Summary
Dermatofibrosarcoma protuberans (DFSP) was first described by Taylor in 1890 as a keloid sarcoma.[1]. We report a case of a 44-year-old man, with a long history of smoking, who was referred to our department for a swelling on his left breast. His family history was unremarkable of breast cancer. Clinical examination showed a firm, tender, mobile mass measuring 4 cm in the greatest diameter, located in upper union quadrant of the left breast and invaded the skin (Figure 1). Ultrasonography revealed an indistinct limited mass with central vascularization, measured 4 cm, and mammography demonstrated a nonhomogeneous and hyperdense lesion, which classified the tumor as a BI-RADS 4B (Breast Imaging Reporting and Data System 4B; Figure 2).
