256 cases of solitary chondroma, multiple chondromas and chondromatosis were analysed. 200 cases had a long term follow up of 1-50 years (average 10 years). Recurrence after surgical removal is rare. It is exceptional for malignancy to develop in chondromas of the hand. Malignant degeneration (chondrosarcoma, fibrosarcoma, etc.) was found in 12% of the solitary chondromas and in 32% of the multiple chondromas and chondromatosis involving the bones elsewhere than in the hand. The first of these figures is probably excessive, since many of the solitary chondromas elsewhere than in the hand remain asymptomatic and unrecognised; but the second figure is probably too low; since the risk of sarcomatous degeneration remains present throughout the patient's life.
