Tenosynovial chondroma of the hand: a case report with a brief review of the literature.

Tumors of hyaline cartilage occurring in the soft tissues of the hands and feet arise by metaplasia from the synovium of tendon sheaths and have a benign clinical evolution. Although recurrences may develop, they show no tendency to metastasize. The majority of these tumors prove to be diagnostic difficulties because of the alarming histologic atypia they display. We report a case of tenosynovial chondroma of the hand and briefly review the salient features of these lesions.
