Secondary synovial chondromatosis of the shoulder.

Synovial chondromatosis is classified as either primary or secondary. Primary synovial chondromatosis results from a proliferation of chondrocytes in the synovial membrane leading to the formation of cartilaginous loose bodies. Secondary synovial chondromatosis is a rare condition characterized by the growth of separated particles from the articular cartilage or osteophytes in joint diseases. The present article aims to report the secondary chondromatosis of the shoulder and to discuss the clinical manifestations, pathogenesis, diagnosis, histological findings and management of this condition.
