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.

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.
