[Chondrosarcoma of the hand]

The authors report 5 cases of chondrosarcoma of the hand brought together over a period of 20 years. The series comprises 3 men and 2 woman of average age 42 years. In two cases the tumour arose from degeneration in a preexisting lesion of Ollier's disease. Diagnosis was made on clinical and radiological criteria. Confirmation of the diagnosis by histological examination proved to be difficult in 2 cases. The treatment was surgical, with ray amputation in 3 cases and curettage with bone graft in the other 2. None of the patients had a recurrence at 4.5 years mean follow-up.
