Microscopic findings of the renal biopsy. Periodic acid-Schiff staining shows tubular necrosis and pigments of various colors ranging from yellow to brown in the proximal tubular epithelial cells (a: ×400, b: ×400). a Black arrow shows loss of the brush border and swelling of the tubular epithelium. b Black arrow shows detachment of tubular epithelium from the basement membrane. Black arrowhead shows coagulative necrosis of the tubular epithelium. c Mesangial proliferation in the glomeruli (c: ×400). Immunofluorescence shows granular mesangial staining for immunoglobulin A (IgA) (d) and C3 (e), without staining for IgG, IgM, and C1q. Electron microscopy shows para-mesangial electron-dense deposits (f: ×8000, black arrow)
