What is pigmented villonodular synovitis?
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. The mass or tumor that results from this overgrowth is not cancerous and does not spread (metastasize) to other areas of the body.
Is PVNS life threatening?
PVNS is not life threatening. However, if left untreated it can lead to serious complications such as permanent joint deformity and osteoarthritis. In severe cases, it could result in amputation of the affected limb.

Can PVNS become malignant?
Malignant PVNS is an extremely rare condition but established concept involving a malignant form of GCTTS or PVNS. Enzinger and Weiss proposed the definition of the condition as a malignant lesion occurring with concomitant or previously documented conventional PVNS at the same site [1].
How long does it take to recover from PVNS surgery?
How long does it take to recover from PVNS surgery? An individual can expect recovery to take a minimum of six weeks; a full recovery may take several months depending on the severity of PVNS disease. Physical therapy is important to regain mobility and strength in surrounding muscles.
Can PVNS be malignant?
Malignant pigmented villonodular synovitis (PVNS) (or malignant giant cell tumor of tendon sheath (GCTTS) is an extremely rare condition defined as a malignant lesion occurring with concomitant or previously documented PVNS at the same site.
What causes Villonodular synovitis?
What Causes Pigmented Villonodular Synovitis (PVNS)? The exact cause of PVNS is unknown. In a normal joint, the synovium is a thin layer of tissue that surrounds all of your joints and tendons—the connective tissues between muscles and bones.

What is pigmented villonodular bursitis (PVNB)?
Other sites with a synovial lining that may be affected include bursae and tendon sheaths. The condition is then known as pigmented villonodular bursitis(PVNB) when in a bursa and tenosynovial giant cell tumor when in a tendon sheath. PVNS/B/TS are divided into a localized and diffuse forms:
