title: Pigmented villonodular synovitis of the temporomandibular joint. Case Report.
abstract: Pigmented villonodular synovitis is a lesion containing giant cells and, because of its tendency to recur, it is easily confused with a malignant process. However, careful review of the histological material will reveal that there is no nuclear atypism or mitotic figures. Also, there have been no reports attributing metastases or death to thid disease. The clinical course of our case was definitely benign.
