Giridhar Kumar , Gayathri MN, and Shilpa K

Pigmented villo nodular synovitis is an unusual benign disease of unknown cause producing circumscribed or diffuse thickening of the synovial lining of joints, tendon sheath and bursae. The clincal and pathological distinction between Pigmented villo nodular synovitis and malignant synovioma has in the past often posed difficult problems; there is no doubt that many amputations have been performed for what is now considered to be an entirely benign condition, mistakes may still be made by these who are unfamiliar with the two conditions.The purpose of the present report is to review the literatures on Pigmented Villo nodular synovitis and to present information with a case studied, in which histological material, detailed clinical history and aggressive presentation of benign condition are available.
