Pigmented Villonodular Synovitis of the Wrist Joint

Pigmented villonodular synovitis of the wrist with penetration into bone.

Invasion and erosion of bone in nodular synovitis (histiocytic xanthomatous granuloma, xanthoma, giant-cell tumour, benign synovioma) are found fairly frequently in circumscribed lesions of the tendon sheaths of hands and feet. Fletcher and Horn (1951) in particular called attention to this. Bone involvement in diffuse forms, namely “ pigmented villonodular synovitis, bursitis and tenosynovitis...

Localized Pigmented Villonodular Synovitis of the Proximal Tibiofibular Joint

Pigmented villonodular synovitis (PVNS) is a rare disease. It is a benign neoplastic process typically affecting young to middle-aged adults and most commonly involving the knee, hip, and shoulder joints. The symptoms include diffuse pain and swelling with discomfort. We report a rare case of localized PVNS originating at the proximal tibiofibular joint in a 39-year-old female patient with radi...

Pigmented villonodular synovitis.

Pigmented villonodular synovitis (PVS) is an uncommon, usually monoarticular disorder encountered mainly in adults. A boy and a girl, both 7 years old, were referred because of recurrent knee effusions. Both were medically treated for other rheumatic disorders for five years. PVS was diagnosed by arthroscopy and synovectomy was curative in both cases.

The knee PVNS presents as a localized or diffuse form. Diagnosis if often delayed and permanent joint damage occurs with advanced disease. Ultrasound examination shows fluid collection and synovial hypertrophy. Magnetic resonance imaging helps in cl...
