Synovial chondromatosis is a rare, benign, chronic, progressive and proliferative lesion that usually affects large joints. This disease is characterized by the development of cartilaginous nodules within the space of synovial joints, tendon sheaths or cases; the nodules subsequently degrade, detach and form free-floating, calcified bodies within the joint space. In 1933, Axhausen described the first case of synovial chondromatosis affecting the temporomandibular joint. The aetiology still remains unknown, but a history of trauma and inflammation is often found. Clinical symptoms of chondromatosis affecting the TMJ are often characterized by swelling, pain, headache, crepitation, malocclusion and joint dysfunction. The big challenge concerning synovial chondromatosis is to suspect and establish a correct diagnosis. These nonspecific initial signs and symptoms may mimic other nonspecific TMJ's diseases and can easily lead to a delay in diagnosis or a misdiagnosis. Here we present a case of synovial chondromatosis of the TMJ and the appropriate diagnostic and treatment performed.
