What is focal nodular synovitis?

What is focal nodular synovitis?

Localized nodular synovitis, also termed “synovial giant cell tumor,” is a benign lesion characterized by localized synovial proliferation. This condition is found predominantly in the tendon sheaths or joints of the fingers and toes [1–3].

What is diffuse synovitis of the knee?

Synovitis is a term given to a condition caused by the abnormal inflammation of the knee lining. This tissue is known as the synovium. While the exact cause of inflammation can vary, when it occurs, it can result in chronic pain, swelling, catching, or knee stiffness.

Can PVNS spread to other joints?

The mass or tumor that results from this overgrowth is not cancerous and does not spread (metastasize) to other areas of the body. However, PVNS is a progressive disease. It slowly worsens and can lead to bone damage and arthritis. PVNS usually affects the knee, although it can affect other joints as well.

Can PVNS be 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].

What is the synovitis?

Listen to pronunciation. (SIH-noh-VY-tis) Inflammation (swelling, pain, and warmth) of a synovial membrane, which is a layer of connective tissue that lines a joint, such as the hip, knee, ankle, or shoulder. Synovitis is caused by some types of arthritis and other diseases.

What is synovial Osteochondromatosis of knee?

Synovial chondromatosis (also called synovial osteochondromatosis) is a rare, benign (noncancerous) condition that involves the synovium, which is the thin layer of tissue that lines the joints. Synovial chondromatosis can arise in any joint in the body, but most commonly occurs in the knee.

How do you treat knee synovitis?

Treatment for synovitis usually consists of rest and anti-inflammatory medications. Medications may include oral drugs known as DMARDs (disease-modifying antirheumatic drugs) and, in some cases, steroid injections.

Is PVNS life threatening?

PVNS has been described as a growth or a tumor in the lining of the joint. While it is accurately labeled as a tumor, it is not cancer and it is not typically life-threatening.

Does PVNS show on xray?

The hypertrophic synovium appears as a soft tissue mass, which on account of haemosiderin, may appear slightly hyperdense compared to adjacent muscle. Calcification is very rare in the synovial mass (cf. synovial sarcoma where it is common). Erosions are often well seen on CT.

Is PVNS serious?

Can PVNS be cured?

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.

What does pigmented villonodular synovitis mean for You?

What is pigmented villonodular synovitis? Pigmented villonodular synovitis (PVNS) is a joint problem that usually affects the hip or knee. It can also occur in the shoulder, ankle, elbow, hand or foot. When you have PVNS, the lining of a joint becomes swollen and grows. This growth harms the bone around the joint.

When does pigmented villonodular bursitis ( PVNB ) occur?

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 form: Typically PVNS is a monoarticular condition and joints with large synovial surfaces are predictably most frequently affected.

Which is the best way to treat villonodular synovitis?

There is no standard method of management of this lesion. Open surgery is a classical and effective method for treatment. Arthroscopic synovectomy, however, has gained popularity, and has several advantages over the open technique particularly in exclusively articular cases.
