Electron Microscopy. There is marked thickening of the glomerular basement membrane due to the presence of numerous electron dense deposits located at different levels. The deposits vary in size, tend to be spherical in shape and blend together. Under higher magnifications, they did not exhibit a fibrillary or micro-tubular substructure. Notice a thin subendothelial layer of duplicated basement membrane, also containing electron dense deposits, with cellular interposition. The capillary lumen appears significantly reduced in diameter. Also notice electron dense deposits present in the basement membrane of Bowman's capsule on the right upper corner (Uranyl acetate & lead citrate × 35,000).
