Pigmented villonodular synovitis (PVNS) of the knee mimicking septic arthritis in a paediatric patient: A case report

Pigmented villonodular synovitis (PVNS) is a benign but rare proliferative disorder of the synovium. It commonly occurs in the adult population and usually presents as a monoarticular disease. There are two types of PVNS, namely the localised and diffused type. The disease is often misdiagnosed due...
