Villonodular synovitis (pigmented), also known as PVNS, is a rare joint condition that occurs in the lining of the joints, tendons, and bursae. This condition is characterized by the overgrowth of the synovial tissue, which lines the joints and produces fluid that lubricates and nourishes the joint. PVNS is most commonly found in the knee joint, but it can also affect other joints in the body.

The exact cause of PVNS is unknown. However, some researchers believe that it may be caused by a genetic mutation or a dysfunction in the immune system. The condition may also be related to previous joint injuries or trauma.
