Is pigmented villonodular synovitis cancerous?
Diseases & Conditions Pigmented villonodular synovitis (PVNS) is a condition that causes the synovium—the thin layer of tissue that lines the joints and tendons—to thicken and overgrow.

PVNS is caused by overgrowth and thickening of the synovium. Synovium, which is also called synovial lining, is a thin capsule that encloses the joint and produces a lubricating fluid called synovial fluid. All moving joints in the body have synovium, which reduces friction in the joint structures as the joint moves.
Is pigmented villonodular synovitis painful?
