[Soft-tissue chondroma of the hand. A new case]

The authors report the case of a multilocular tumour of the soft tissues of the hand and wrist which was removed by excision biopsy and which proved to be a chondroma arising from the soft tissues. Soft tissue chondromas consist of islands of heterotopic cartilaginous tissue and can equally affect the viscera as well as the limbs. The hypothesis that microtrauma is involved in the aetiology of this condition has yet to find any factual support. Simple excision-biopsy should suffice to treat the condition but care should be taken to make the excision complete if recurrences are to be avoided.
