[Transformation of dermatofibrosarcoma protuberans on a fibrosarcoma-A case report]

The dermatofibrosarcoma protuberans is a rare cutaneous mesenchymal tumor characterized by a low potential of malignancy with a very low rate of metastasis but an important rate of local recurrence. Its transformation on a fibrosarcoma is exceptional, responsible of a higher metastatic potential. This transformation leads to a better surveillance. With a case report and literature review we will try to remember epidemiological, physical, histological, therapeutic, and outcome particularities of this entity
