Figure 2: H and E staining under light microscopy showing tubular necrosis also (arrow). Renal biopsy report Light microscopy Multiple section from single corticomedullary core stained with H and E, PAS, MT, and Silver show 21 glomeruli. Cortex reveals necrosis which shows ghost outline of glomeruli and proximal convoluted tubule. A few distal tubule in the cortex and medulla appear viable. No viable glomeruli noted in the core. Immunofluorescence studies. Tissues for IF also show cortical necrosis. Medulla appears viable.
