Darier and Ferranddermatofibrosarcoma (DFS) is a cutaneous mesenchymal tumor of intermediate malignancy. It is a rare but not exceptional tumor, representing 0.1% of malignant skin tumors, slow growth, very high risk of local recurrence, but low metastatic potential. We report a case of malignant multi-recurrent degeneration in sarcoma of DarierFerranddermatofibrosarcoma in a 46 year-old patient , and this despite having evoked early diagnosis and performed a large surgical resection. This observation illustrates the frankly malignant but exceptional sarcomatous transformation.
