Description
Summary:Pigmented villonodular synovitis (PVNS) is a benign proliferative disorder of the synovium of joints. It occurs most commonly in the knee joint. The disease presents in two forms: diffuse or localized. The diffuse form of PVNS involves virtually the entire synovial lining of the affected joint. The localized form of PVNS is a rare pathologic entity characterized by a limited involvement of the synovium and generally presented as a nodular, pedunculated lesion protruding into the articular cavity. The lesion of localized form of PVNS is usually easily identified with arthroscopy and can be removed arthroscopically, We expreienced a patient who was diagnosed as localized PVNS, whose main symptoms were pain and mass on the medial side of the knee joint. On physical examination, there were no abnormal evidences. So, diagnostic arthroscopy was performed, and typical findings of localized PVNS were identified. Complete removal of the lesion was done arthroscopically. Postoperatively, the patient was completely symptom free.
