Antineutrophil cytoplasmic antibody-associated vasculitides include all except
Wegener&;s granulomatosis, microscopic polyangiitis, and Churg-Strauss syndrome are small- to medium-vessel vasculitides linked by overlapping pathology and the presence of antineutrophil cytoplasmic antibodies (ANCA). Commonly referred to as the ANCA-associated vasculitides, POLYAERITIS NODOSAIt is a multisystem, necrotizing vasculitis of small and medium-sizedmuscular aeries in which involvement of the renal and visceral aeriesis characteristic.Polyaeritis nodosa does not involve pulmonary aeries, although bronchial vessels may be involved.Antibodies against myeloperoxidase or proteinase-3 (ANCA) are rarely found in patients with polyaeritis nodosa.Harrison 19th e pg:2187
