Multiple chondrosarcomas in a hand: a case report

In a patient with multiple enchondromas limited to the ring finger and the fifth ray of the left hand, four of the enchondromas underwent simultaneous malignant degeneration during a 7 year observation period. Roentgenograms showed the initial cortical expansion changing to cortical destruction and soft tissue invasion. Ray resection of the involved digits was performed with a good functional result.
