Enchondromas are common bone tumors that preferentially affect fingers. It is essential to know that 10% of chondrosarcomas are secondary to preexisting lesions. We present the case of a patient followed up for 30 years for a chondroma of a finger. Following increasing pain, curettage associated with radius bone graft was performed. However, the pain persisted postoperatively and inflammation and edema of the wrist and fingers appeared. Excisional biopsy was performed and the anatomopathologic results confirmed the sarcomatous transformation of the enchondroma and its dissemination to the radius. The oncological rules of surgery must be applied, even if the tumor appears to be benign in order to avoid dramatic consequences for the functional and vital prognosis of the patients.
