Abstract

Pigmented villonodular synovitis (PVNS) is a rare, benign proliferative synovial disease that can affect the hallux metatarsophalangeal joint and manifest as secondary hallux rigidus. Clinical suspicion sometimes occurs only intraoperatively, when a synovium with blackened foci of hemosiderin deposits is found. We present a rare case of PVNS in the hallux metatarsophalangeal joint, treated surgically with synovectomy and cheilectomy. Level of Evidence V; Diagnostic Studies; Expert Opinion
