vasculitis

 [vas″ku-li´tis]
inflammation of a blood or lymph vessel; see arteritis, lymphangitis, and phlebitis. Called also angiitis.
Churg-Strauss vasculitis churg-strauss syndrome.
hypersensitivity vasculitis a group of systemic necrotizing vasculitides thought to represent hypersensitivity to an antigenic stimulus, such as a drug, infectious agent, or exogenous or endogenous protein; all disorders in this group involve the small vessels.
necrotizing vasculitis see systemic necrotizing vasculitis.
nodular vasculitis a chronic vasculitis of unknown etiology found predominantly below the knees, especially on the calves in young and middle-aged women, characterized by the presence of painful, reddish blue nodular lesions that may ulcerate, leaving scars, or resorb, leaving atrophic depressions. In the late stages, there is replacement of the subcutaneous fat by fibrosis and atrophy (wucher atrophy).
systemic necrotizing vasculitis any of a group of disorders characterized by inflammation and necrosis of blood vessels, occurring in a broad spectrum of cutaneous and systemic disorders. It includes Churg-Strauss syndrome, polyarteritis nodosa, the various kinds of hypersensitivity vasculitis, and other conditions. Called also necrotizing vasculitis.

necrotizing vasculitis

an inflammatory condition of blood vessels characterized by necrosis, fibrosis, and proliferation of the inner layer of the vascular wall. Some cases result in occlusion and infarction. Necrotizing vasculitis may occur in rheumatoid arthritis and is common in systemic lupus erythematosus, periarteritis nodosa, and progressive systemic sclerosis. The condition is usually treated with corticosteroids.

necrotizing vasculitis

vasculitis, caused by deposition of immune complexes within blood vessel walls; characteristic of rheumatoid disease; may cause digital or foot ulceration

necrotizing

causing necrosis; exuding a brown to green, putrid discharge containing tissue debris.

necrotizing epithelioma, necrotizing calcifying epithelioma
necrotizing hepatopancreatitis
disease of shrimps caused by a small obligate intracellular unidentified bacterium; subacute to chronic syndrome with cumulative mortality of up to 90%.
necrotizing panniculitis
multifocal, erythematous, nonpruritic cutaneous lesions which ulcerate in the center and discharge seropurulent exudate; identifiable on histopathological examination.
necrotizing scleritis
a rare eye lesion, inflammatory proliferation of the anterior sclera, in dogs.
necrotizing ulcerative gingivitis
see necrotizing ulcerative gingivitis.
necrotizing vasculitis
important feature of the Arthus reaction; damage to the endothelium results from deposition of immune complexes in the vessel wall, usually on the basement membrane of the endothelium.

Necrotizing vasculitis can sometimes be very difficult to identify because the affected vessels may be completely necrotic.

Necrotizing vasculitis is usually found within the inflamed, but nonnecrotic area in the lesion, and this is where it should be sought.
Necrotizing vasculitis is most readily identified when it is "eccentric," affecting the vessel focally and leaving the rest of the wall uninvolved.
