Soft tissues chondromas of the hand: a report of five cases.

Soft tissue chondromas are rare slowly-progressing benign tumours. We report 5 new cases of soft-tissue chondromas of the hand. The median age at the time of diagnosis was 38 years. The evolution ranged from one month to 5 years. Standard radiographs showed variable images depending on the degree of calcification. An excision biopsy was performed in all patients. A well encapsulated and limited tumour was found at surgery. Positive diagnosis was provided by the pathology examination. Simple excision-biopsy should suffice to treat the condition but care should be taken to make the excision complete in order to avoid recurrence.
