Immunofluorescence microscopy demonstrated linear (2+) staining along the glomerular capillary loops for IgG (Figure 1) supported the diagnosis of anti-GBM disease.
Light microscopy revealed 44 cellular crescents in 72 glomeruli.

Light microscopy revealed 72 glomeruli, of which 8 were globally sclerosis, 2 were segmental sclerosis, 39 were large cellular crescents, 5 were small cellular crescents, cellular crescents account for 61%, which suggested crescentic glomerulonephritis (Figure 2).
