title: Pigmented villonodular synovitis secondary to laceration of the perforating branch of the peroneal artery.
abstract: A case of peroneal artery injury subsequently developed into a lesion resembling an extra-articular tenosynovial giant cell tumor, which is a type of pigmented villonodular synovitis (PVNS). This case supports the hypothesis that accident trauma, such as a vascular injury, can be the etiology of PVNS.
