Synovial chondromatosis is a cartilaginous metaplasia of the synovial tissue of joints. It is an uncommondisease whose etiology is unknown. This benign synovial process involves the formation of cartilaginous nodules(loose bodies) in the synovium and within the articular space. Synovial chondromatosis mainly affects large synovialjoints and the main symptoms are pain and swelling. Diagnosis can be made by panoramic radiograph, computedtomography scan and magnetic resonance imaging of the joint. The main treatment includes complete removal ofthe loose bodies in conjunction with excision of the affected synovium. We report two cases of synovial chondromatosislocated in an uncommon regions: in the esternoclavicular joint and in the temporomandibular joint. We alsomake a literature review about synovial chondromatosis.
