Synovial chondrometaplasia of the temporomandibular joint: report of case.

Abstract

A case of synovial chondrometaplasia of the temporomandibular joint is presented with a discussion of the pathologic findings, diagnosis, and treatment. This is a highly uncommon, benign lesion of this joint that affects women more often than men. Since the histologic appearance of some of the tissue cells may resemble malignant changes, care should be taken not to confuse this condition with chondrosarcoma.
