Recurrent solitary osteochondroma of the metacarpal: a case report.

Osteochondromas are the most common benign bone tumours and account for 20 to 50% of benign bone tumours and 10 to 15% of all bone tumours. They usually occur in long bones; 40% occur around the knee joint, but in the hand they are uncommon and usually affect the proximal phalanx. The metacarpal is rarely involved. We report a 32-year-old man with a recurrent solitary osteochondroma of the metacarpal.
