title: Primary synovial osteochondromatosis of the first metatarsophalangeal joint.
abstract: Synovial osteochondromatosis is an uncommon disorder, generally seen in large joints such as the knee, elbow, shoulder, hip and ankle. We report a 35-year-old man with synovial osteochondromatosis of the metatarsophalangeal joint of the great toe. Despite the rarity of the location, the radiographic appearance ought to suggest the diagnosis. Histological confirmation is required, since malignancy cannot be totally ruled out clinically and radiographically.
