title: Pigmented villonodular synovitis of the temporomandibular joint.
abstract: Pigmented villonodular synovitis (PVNS) is a relatively rare disease, affecting the synovial-lined joints. PVNS was first fully described by Jaffè in 1941, who considered it to be a benign inflammatory state of the synovium of an uncertain etiology. Reports of this disease in the temporomandibular joint (TMJ) are extremely rare. The authors report a case of a 38-year-old woman affected by pigmented villonodular synovitis of the TMJ. Clinical examination revealed the presence of a preauricular mass in the left side; a computed tomography scan showed a 3.0 x 2.0 cm preauricular mass in close continuity to the TMJ capsule. The purpose of this report is to describe the clinicopathological features of a case involving the TMJ. The previously reported cases in the literature are also reviewed.
