title: [An autopsy case of Goodpasture syndrome preceded with membranous glomerulonephritis].
abstract: Goodpasture syndrome (GS) is an autoimmune disorder characterized by the association of pulmonary hemorrhage and rapidly progressive glomerulonephritis. The pathogenesis of GS is still unknown, but was shown to be the result that antibodies directed against glomerular basement membrane (GBM) antigens could injure both glomerular and pulmonary alveolar basement membrane. And membranous glomerulonephritis (MGN) is a glomerular disease characterized by epimembranous immune deposits and basement membrane thickening. MGN typically presents with the onset of nephrotic syndrome, but it often presents with only asymptomatic proteinuria. We reported an autopsy case of GS preceded with MGN. A 70-year-old man was admitted to our hospital with acute renal failure in May 2, 1996. Percutaneous renal biopsy demonstrated a crescentic glomerulonephritis associated with MGN and linear immunofluorescent staining of the basement membrane with antibodies to IgG. Two weeks later on admission he began to develop slight hemoptysis and chest X-ray showed pulmonary hemorrhage, Furthermore, his serum anti-GBM antibodies titer was very high. He was diagnosed as GS associated with MGN and treated with plasma exchange, glucocorticoid, and cyclophosphamide. Though his symptom was improved for intensive support, he suddenly died on June 22. Autopsied lungs showed focal pulmonary hemorrhage, but were not considered to be life-threatening. The cause of the death remained unclear.
