[Chondrosarcoma of the hand arising from multiple enchondromas: a case report].

Malignancy occurs more often in multiple enchondromas than in solitary enchondromas. In the hands the rate is about 14%. We amputated the third ray of the hand in a young man with recurrence of an enchondroma. The histology showed a low grade chondrosarcoma. The patient had no tumour recurrence or metastasis in the following 5 years. We describe the evaluation as well as the treatment and outline the literature.
