Chondrosarcoma of the hand.

A case of chondrosarcoma of the hand recurred 4 times over a period of 32 years. Forty-seven cases of hand chondrosarcomas have been found in the literature. Histological diagnosis is difficult in differentiating chondrosarcomas from benign chondromas. Pain and swelling are the main symptoms of recurrence. The diagnosis is established by arteriography and excisional biopsy. Extraskeletal hand chondrosarcomas do not metastasize and other hand chondrosarcomas do so only rarely. Block excision of localized amputation is the treatment of choice.
