Pigmented villonodular synovitis (PVNS) is a rare benign proliferative growth of the synovium of obscure aetiology. PVNS may present as a localized nodule, usually arising in the hand, or as a diffuse process, usually found in the knee. The optimal treatment is surgery. As surgery may not eliminate all affected tissue, postoperative radiosynoviorthesis is discussed to remove residua of the synovial membrane. There is a low rate of malignant change but the lesion has the ability for reactivated growth and a tendency to recur. This paper reports the case of a rare localizated Pigmented villonodular synovitis of the ankle.
