[Diffuse pulmonary hemorrhage due to capillaritis in a patient with typical periarteritis nodosa and necrotizing glomerulonephritis. Relationship with overlapping vasculitic syndrome and Wegener's granulomatosis].

Clinical and pathological postmortem study of a patient with NPA which died due to a fulminant pulmonary hemorrhage. In the postmortem study, diffuse pulmonary capillaries was observed as the cause of the disease, as well as lesions of necrotizing glomerulonephritis with granulomas, within the framework of a typical NPA. Correlation with the NPA-type overlapping polyangiitic syndrome and microscopic polyarteritis are discussed, as well as the correlation between the latter and Wegener's granulomatosis.
