Dermatofibrosarcoma protuberans is a superficial mesenchymal cutaneous tumor of essentially local malinancy, located more often in the trunk and extremities. This tumor is usually diagnosed after multiple recurrences. We report two cases of rare mammary localisations of dermatofibrosarcoma protuberans in 2 patients aged 39 and 43 years respectively, the two lesions sized 35 x 45 mm were treated by wide excision and reconstruction with a dorsal flap; in the second case.
