Temporomandibular joint synovial chondromatosis.

Synovial chondromatosis (SC) is a rare, benign cartilaginous metaplasia that affects the joints, usually only one joint. Chondromatosis is a hard to diagnose disease because of its somewhat vague symptoms, especially those in the temporomandibular joint (TMJ), which does not fit those from the most prevalent disease sites (knee, elbow and shoulder). There is only one case of TMJ chondromatosis in the Brazilian Literature. The goal of the present investigation is to report a case of TMJ chondromatosis, discussing its pathological aspects and treatment.
