Figure 1From: A case of myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA)-associated glomerulonephritis and concurrent membranous nephropathy Light microscopic findings. Periodic acid-Schiff’s staining reveal a necrotizing extracapillary proliferative glomerulonephritis with crescent and many infiltrated mononuclear cells in the tubulointerstitium (A: original magnification × 200). A glomerulus with fibrocellular crescent and thickened glomerular basement membrane (GBM) (B: original magnification × 400). A glomerulus with fibrocellular crecent and thickened glomerular basement membrane (GBM) (Periodic acid-Schiff’s stain, original magnification × 400).Back to article page
