Pigmented villonodular synovitis (PVNS)

Pigmented villonodular synovitis (PVNS) is a rare benign proliferative condition affecting synovial membranes of joints, bursae or tendons resulting from possibly neoplastic synovial proliferation with villous and nodular projections and hemosiderin deposition. PVNS is most commonly monoarticular (~70% knee joint) but occasionally it can be oligoarticular. The histology of PVNS can look similar to some aggressive neoplasms (rhabdomyosarcoma, synovial sarcoma, epithelioid sarcoma) and imaging, therefore, has a crucial role in guiding the pathologist.
