Synovial chondromatosis (SC) is a metaplasia of the sinovial membrane that generally affects big joints like hip and knee, with the production of numerous little nodules that can detach from the synovia and become “loose bodies” within the joint. First description of the rare localization of SC in the temporo-mandibular joint (TMJ) was given by Axhausen in 1933. Though malignant transformation of this tumor-like affection is told to be really rare, complication of this affection are a chronical inflammatory status of the synovial membrane, with pain and swelling, limitation of the movements of the mandible, and extension to the paracondilar tissues, until basicranium. Aim of the authors was to describe the uneasy diagnosis and the treatment of a case of SC of the TMJ referred to their Department in April 2009.
