[Acute primary alveolar hemorrhage or Goodpasture's syndrome?]

We report a case of idiopathic diffuse alveolar haemorrhage with fatal outcome in a 23 year old man. In the absence of any renal abnormality of circulating antiglomerular basement antibody the diagnosis of Goodpasture's syndrome was made taking into account the history and the autopsy evidence of linear deposits of immunoglobulin on the glomerular basement membranes.
