Pigmented villonodular synovitis (PVNS) is a type of benign (non-cancerous) tumor that arises from the soft connective tissue of joints. Any joint can be affected, although the tumor is most commonly found in the knee or hip joint. Although it can be painful, PVNS usually does not spread. It does, however, have a high rate of recurrence after surgery.
- PVNS usually has a good outcome because it is usually not considered an aggressive tumor.
- It is sometimes completely cured through surgery, although it recurs in about half of all cases.
- It is rare in children.
- The cause is unknown.
