Abstract

Pigmented villonodular synovitis (PVNS) in ankle is relatively uncommon. This disorder results in increased proliferation of synovium causing villous or nodular changes containing histiocytes, fibroblasts, multinucleated giant cell, and hemosiderin. PVNS is classified into two different type : localized and diffuse. Diffuse type of PVNS in ankle is more common than localized type. Also, recurrence of diffuse type is more frequent. We report a case of diffuse type of PVNS which was recurred soon after the excision.
