Two cases of Localized Pigmented Villonodular Synovitis in the Ankle Joint

Abstract

Two cases of localized pigmented villonodular synovitis (PVS) in the talocrural joints of a 36 and a 27 year old women are presented. In one case, synovial invasion into the fibula was seen intraoperatively, and total synovectomy and curettage was performed. 7 years postoperatively, osteoarthritis in one ankle progresses without local recurrence. In the other case, erosion of articularcartilage was seen, and total synovectomy was performed.
Because of invasion into the bone, it is important to diagnose PVS early and proceed with treatment.
