고관절에 발생한 색소융모 결절성 활액막염 = Pigmented Villonodular Synovitis of the Hip Joint

다국어 초록 (Multilingual Abstract)

Pigmented villonodular synovitis is a kind of benign inflammatory lesion involving synovial membrane, characterized by yellow-grayish colored villous nodules of synovial membrane, formed by accumulation of cholesterol and hemosiderin with numerous cleftings of synovial membrane. This occurs most commonly in the knee joint as a monoarticular proliferative process. The deveiopment of this disease in the hip joint is rare and moreover, the diagnosis is not easy. Early diagnosis of hip joint involvement is important because destruction of femoral head and acetabulum is the ultimate outcome if treatment is not initiated. A definitive treatment for this disease process is not yet known. In this paper, we report a case of pigmented villonodular synovitis of the hip joint with a review of the literature. It was identified in a 23-year-old young lady who was treated by synovectomy.
