synovitis

 [sin″o-vi´tis]
inflammation of a synovial membrane, usually painful, particularly on motion, and characterized by fluctuating swelling, due to effusion in a synovial sac. It may be caused by rheumatic fever, rheumatoid arthritis, tuberculosis, trauma, gout, or other conditions.
Events involved in the pathogenesis of rheumatoid synovitis progress from left to right. M = macrophage; T = T lymphocyte; B = B lymphocyte; P = plasma cell; IL = interleukin; TNF-α = tumor necrosis factor α; TGF-β = transforming growth factor β; GM-CSF = granulocyte-macrophage colony-stimulating factor; RF = rheumatoid factor; PGE2 = prostaglandin E2; C = complement. From Goldman and Bennett, 2000.
dry synovitis synovitis with little effusion.
purulent synovitis synovitis with effusion of pus in a synovial sac.
serous synovitis synovitis with copious nonpurulent effusion.
synovitis sic´ca dry synovitis.
simple synovitis synovitis with clear or slightly turbid effusion.
tendinous synovitis inflammation of a tendon sheath.
villonodular synovitis proliferation of synovial tissue, especially of the knee joint, composed of synovial villi and fibrous nodules infiltrated by giant cells and macrophages.

Jaffe was the first to describe pigmented villonodular synovitis (PVNS) as a chronic proliferative disease that occurs in the joint, tendon and bursa synovium.1 According to Jaffe, PVNS is characterised by thickened and hyper- plastic synovia organised into villi and nodules, which lead to the deposition of intra-cellular haemosiderin pigments.
