AFONSO, Carolina T. M. et al. Sinovite Vilonodular do Ombro: Um Caso de Sucesso Tratado Artroscopicamente. Rev. Port. Ortop. Traum. [online]. 2019, vol.27, n.2, pp.113-120. ISSN 1646-2122.

Pigmented villonodular synovitis, which belongs to the group of giant cell tenosynovial tumors, is a rare benign disease, with an incidence of 1.8 cases per million inhabitants per year. It occurs by proliferation of the synovial membrane of the joints, bursae and tendinous sheaths, with pigmentation by haemosideria deposits. It mainly affects individuals between the ages of 30 and 40. Affects the knee in about 80% of the cases and the shoulder in only 2.4% of the cases. Its clinical manifestations are nonspecific and on XRay this entity usually goes unnoticed. Magnetic Resonance Imaging is not specific for diagnosis but is useful for differentiating it from other pathologies and stratifying the extent of the disease. Definitive diagnosis is histological. Synovectomy is the indicated treatment. Knowing the subtype of the disease is crucial for choosing the surgical method: open or arthroscopic. We present a case of a localized giant cell tenosynovial tumor of the shoulder treated with excision by arthroscopy. The treatment was effective, with no recurrence to date.

Palabras clave : Synovitis villonodolar pigmented; Shoulder; Arthroscopic treatment.
