PRIMARY synovial chondromatosis is a rare condition in which foci of cartilage develop in the synovial membrane of joints, bursae and tendon sheaths. It typically involves a single large joint in a young adult male. The ectopic foci of cartilage can result in painful joint effusion, and the generation of loose bodies can cause mechanical symptoms. The etiology of primary synovial chondromatosis remains unknown, but metaplastic theory is the most popular hypothesis. The commonly involved joints are knee, elbow, and hip. The shoulder is a rare site of synovial chondromatosis and the extra-articular involvement even rarer, with only few cases presented in literature. This report presents a rare case of primary combined intra-articular and extra-articular synovial chondromatosis of shoulder joint treated with arthroscopy.

Key words: synovial chondromatosis, shoulder, intra-articular, extra-articular, arthroscopy
