| Abstract |
| Pigmented villonodullar synovitis (PVS) occurs
in two forms: diffuse PVS and localized pigmented villonodular synovitis.
In this report, a 40-year-old woman presented with a history of recurrent
episodes of knee locking and pain. Arthroscopy revealed a nodular
pedunculated mass occupying the area anterior to the intercondylar
notch of the femur. Histological examination of the tissue confirmed
the diagnosis of PVS. After surgery, the patients symptoms of pain
and recurrent locking promptly resolved. |
