This report presents a case of synovial cyst of the temporomandibular joint, which is rarely involved in this region. Histopathological characteristics of the cyst are described in detail. The diagnosis differentiating it from ganglion is also discussed, while synovial cyst is a true cyst lined by synovial cells, ganglion is a pseudocyst lined by dense connective tissues. Immunohistochemical staining may be helpful in identifing the lining cells of the synovial cyst.
