Pigmented villonodular synovitis (PVNS) is a relatively rare lesion in the foot and ankle, most commonly involving the ankle joint and atypically, the subtalar and midtarsal joints. It is a benign proliferative disease characterized by an increase in villous or nodular synovium in joints. Resection of the tumor is often indicated in most cases because of the potentially aggressive joint destructive nature of this lesion.
