The localized form of pigmented villonodular synovitis (PVNS) is a rare pathologic entity characterized by limited involvement of the synovium. In the knee joint, which is the most commonly affected joint, the disorder generally presents as a single nodular lesion, or rarely as 2 or 3 multiple nodular lesions into the joint. We report 2 cases of localized PVNS in which multiple nodules were clustered in a limited patella fat pad area. Clustered, multiple nodular lesions in a limited area suggested to us to consider a variant of localized forms.
色素沉着绒毛结节性滑膜炎（PVNS）的局限性形式是一种罕见的病理实体，其特征是滑膜受累有限。在最常受累的膝关节中，该疾病通常表现为单个结节性病变，或极少表现为关节内2个或3个多发结节性病变。我们报告2例局限性PVNS，其中多个结节聚集在有限的髌下脂肪垫区域。有限区域内聚集的多发结节性病变让我们考虑这是局限性形式的一种变体。
