Renal biopsy findings of patient 2. a showed λ linear staining along glomerular capillary wall and tubular basement membrane (× 200). b showed mild segmental mesangial proliferation of glomeruli (PASM+Masson, × 400). c showed fibrillary structure in the peripheral of the protein casts and mononuclear cells in the center (PASM+Masson, × 400). d showed the protein cast was Congo-red positive (× 400). e showed no deposit in the glomeruli on electron microscopy (× 15,000). f showed fine granular deposits along the tubular basement membrane (× 12,000)
