a Electron microscopy demonstrated the subepithelial immune complex deposition with formation of perpendicular spike similar to glomerular membrane (illustrated by Hitachi S-3000N, Japan. The visceral podocyte foot process effacement was also demonstrated. b The electron microscopy demonstrated intracytoplasmic electron lucent vacuoles (arrow) of various sizes in the proximal tubular epithelial cells. Beyond the electron-lucent vacuoles, the vacuoles with lipid droplet (arrowhead, with crescent-like content) also presented within the vacuoles. Original magnifications × 3000. Scale bar 2 μm
