Figure 2: A: Acute exsudative glomerulonephritis with crescent formation (silver staining, magnification x20). B: Erythrocytes trapped inside glomerular capillaries (H&E staining, magnification x20). C: Arteriolar obliteration by a fibrinous thrombus (H&E staining, magnification x40). D: Immunofluorescent staining for C3c showing coarse granular C3c deposits and ribbon-like (subendothelial) deposits along capillary walls (arrow) (magnification x20). E: Immunofluorescent staining for fibrinogen showing a delicate meshwork along the glomerular capillary walls (magnification x20). F: Electron-microscopy: a large subepithelial electron dense deposit (hump, star) and tiny subendothelial deposit (arrow)
