Primary synovial chondromatosis of the temporomandibular joint with suspected traumatic etiology. Report of a case.
Synovial chondromatosis (SC) of the temporomandibular joint (TMJ) is a rare disease that is characterized by the development of nodules of cartilage within the synovial connective tissues of articulating joints. Reports of extracapsular TMJ SC are rare. A case is presented of primary SC of the TMJ with extension to the pterygoid plates, with a suspected traumatic etiology. The differences between primary and secondary SC are discussed.
