Goodpasture's syndrome--local and diffuse deposition of antibody in glomerular basement membrane. Case report.

An unusual case of Goodpasture's syndrome in a 22 year old white female is presented. The diagnosis of antiglomerular basement membrane disease was made on the basis of circulating anti-GBM antibodies in the presence of linear IgG deposits along the glomerular basement membrane by immunofluorescent microscopy. An additional finding was the presence of discrete granular subepithelial deposits on electron microscopy. Possible pathogenetic mechanisms are discussed.
