Pigmented villonodular synovitis (PVNS) is a well-recognized lesion that may affect any joint but is frequently found in the knee. It is a rare condition, especially in the localized form, and is still cause for discussion regarding to its pathogenesis and treatment. We report four cases of localized PVNS each one presenting with different clinical signs and symptoms. In one of our cases, a pedunculated mass and villous-like projections of the surrounding synovium were associated. Each case was studied with magnetic resonance imaging, treated arthroscopically, and the diagnosis confirmed by histological examination. Arthroscopy is an effective tool for both diagnosis and treatment.
色素沉着绒毛结节性滑膜炎（PVNS）是一种公认的病变，可累及任何关节，但常见于膝关节。这是一种罕见的疾病，尤其是局限性形式，其发病机制和治疗仍存在争议。我们报告了4例局限性PVNS病例，每例均表现出不同的临床体征和症状。在我们的其中1例病例中，发现有一个带蒂肿物以及周围滑膜的绒毛样突起。对每例病例均进行了磁共振成像检查、关节镜治疗，并通过组织学检查确诊。关节镜是诊断和治疗的有效工具。
