Abstract

Microscopic polyangitis(MPA) is defined as a systemic necrotizing vasculitis that affects small-sized vessels without granulomata. MPA is associated with focal segmental necrotizing glomerulonephritis. Clinical manifestations are similar to those of polyarteritis nodosa, but are characterized by the presence of rapidly progressive glomerulonephritis and pulmonary involvement, including pulmonary hemorrhage. We reported a case of microscopic polyangitis presenting pulmonary hemorrhage and rapidly progressive glomerulonephritis with a brief review of literatures.
