Histopathologic and clinical course. (a) Light microscope showing 6
glomerulosclerosis, 2 macrocellular, 8 macrocellular fibrous, 3
macrofibrous, 2 microcellular, and 2 microcellular fibrous crescent
formations among the 34 glomeruli. (b) Electron microscopy showing capillary
loops partial compression, parietal cells proliferation, and crescent
formation. Immunofluorescence negative. (c) Time and clinical course of
antineutrophil cytoplasmic antibody-associated glomerulonephritis after
vaccination.. CyC, cyclophosphamide; MPO, myeloperoxidase; SCr, serum creatinine; UTP, 24-h

The kidney biopsy revealed 6 glomerulosclerosis, 2 macrocellular, 8 macrocellular fibrous, 3 macrofibrous, 2 microcellular, and 2 microcellular fibrous crescent formations under light microscope among 34 glomeruli (Figure 1(a)). Electron microscopy showed capillary loops partial compression, parietal cells proliferation, and crescent formation (Figure 1(b)). Figure 1(c) showed the clinical course since the vaccination.
