BARREDA-HALE, Mauricio et al. Primary Synovial Chondromatosis of the Temporomandibular Joint with Temporal Bone Extension. Case Report and Literature Review. Int. J. Odontostomat. [online]. 2019, vol.13, n.1, pp.11-18. ISSN 0718-381X.

Synovial chondromatosis (CS) is a benign lesion that is rare and clinically quite nonspecific. It usually affects the joints of long bones such as the knee, elbow and hip, usually occurring unilaterally. It is believed that in only 3 % of cases of CS the temporomandibular joint. This is a condition its characterized by being a metaplastic synovial connective tissue that manifests itself with the formation of small and multiple cartridges that detach, calcify and form free bodies within the joint space. We present the case of a 55-year-old woman with synovial chondromatosis of the temporomandibular joint, treated for 3 years under the diagnosis of temporomandibular disorders. Despite being considered a benign lesion, this can become locally aggressive, extending as in our report to the cranial fossa, thinning part of the temporal bone.
