Renal biopsy shows the pathological alteration of FSGS (indicated by arrows) Light microscope: glomeruli with segmental sclerosing lesions ((a) hematoxylin-eosin stain; (b) masson stain; (c) periodic acid-Schiff stain; (d) periodic acid-silver methenamine stain, x200 magnification). Immunofluorescent staining shows no immune-type deposits. Electrolyte microscope (e, f): no electron-dense deposits and only visceral epithelial cell foot process effacement. FSGS = focal segmental glomerulosclerosis.
