title: [ANCA-associated lung hemorrhage].
abstract: Pulmonary haemorrhage is a severe complication of small-vessel vasculitis associated with antineutrophil cytoplasm antibodies (ANCA). The main pathologic finding is a pauci-immune capillaritis, although occasionally this lesion is not present. The differential diagnosis includes different diseases and therefore ANCA measurement is important. Two cases of pulmonary haemorrhage associated with ANCA in patients with a clinical picture suggesting small-vessel vasculitis is here reported and a review of the literature is made.
