[Benign course of focal-segmental glomerulonephritis due to antibodies to the glomerular basement membrane]

The authors describe a patient with focal-segmental glomerulonephritis with a benign progress, induced by antibodies to glomerular basement membrane. Clinically the disease advanced in the course of 10 years with painless macroscopic hematuria and persisting microscopic hematuria during the intervals. Histologically, a focal-segmental glomerulonephritis was established, with crescents in certain glomeruli and immunomorphologically with linear depositis of IgG, C3 and febrin.
