case_images: (a) Hematoxylin eosin stained sections show minimal thickening of capillary wall (arrowheads). Arterioles were normal (magnification x400). (b) PAS stained slide showing a hyaline pseudothrombi (arrows) and segmental microaneurysms filled with pale material (stars). Double contours are visible (arrowheads) (magnification x400). (c) Jones silver staining showing thickening of the capillary wall (arrows) and double contours (arrowheads). (d) Electron microscopy show focal loss of fenestrations of endothelial cells (arrowheads) and subendothelial space expansion by electron-lucent material (arrow) (magnification x7000).

case_images: The other glomeruli demonstrated thickening of capillary wall (Figure 1(a)). There were segmental glomerular capillary microaneurysms, filled with pale material, and segmental hyaline thickening of the glomerular basement membrane (Figure 1(b)). Silver staining showed some double contours (Figure 1(c)). Subendothelial space expansion by electron-lucent material was visible (Figure 1(d)).
