title: Transformation of Dermatofibrosarcoma Protuberans into a Fibrosarcoma.
abstract: 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 into a fibrosarcoma is exceptional, responsible for a higher metastatic potential. This transformation implies a closer surveillance. Through a case report and literature review, we will try to expose epidemiological, clinical, histological, therapeutic, and outcome particularities of this entity.
