[Traumatically-induced dermatofibrosarcoma protuberans of the breast].
Dermatofibrosarcoma protuberans is a rare, cutaneous-subcutaneous low grade malignancy. Despite the locally aggressive behaviour, metastases seldom occur. Evidence exists that trauma may be a predisposing factor. Treatment by wide tridimensional excision is recommended. One case of trauma-induced dermatofibrosarcoma protuberans in a 71-year old woman is reported.
