Chondrosarcoma of the trapezium: a case report

Roentgenograms of a 46-year-old Caucasian man with progressive swelling and pain at the base of the thumb who had been treated for arthritis showed an enlargement of the trapezium. The entire bone and surrounding ligaments were removed and an iliac bone graft was used to fuse the trapezoid to the first metacarpal. Sections of the tumor were diagnosed as chondrosarcoma. No recurrence is apparent 3 years after excision.
