Core Tip

Core tip: Synovial osteochondromatosis is a rare condition that arises from metaplasia and proliferation of synovial cells lining a joint space, which can impair joint function. It can be easily overlooked when working up non-specific symptoms such as preauricular pain and swelling. We present the case of a 48-year-old man with a history of significant unilateral temporomandibular joint (TMJ) pain, trismus, and dysphagia who was found to have synovial osteochondromatosis of the TMJ with erosion of the glenoid fossa. The patient underwent resection of the mass and TMJ reconstruction with a rib cartilage graft, resulting in alleviation of symptoms.
