Renal biopsy images. a-c Light microscopy showing significant endothelial and mesangial hypercellularity (Hematoxylin & Eosin [H&E] and Masson stains; 1a × 100, 1b-c × 400). d Light microscopy showing multiple intracapillary hyaline pseudothrombi formation (arrows) but no significant GBM duplication or thickening (Periodic Acid Methenamine [PAM] Silver stain, × 400). e-h Immunofluorescence microscopy indicates granular deposition of IgM 2+, IgG 1+, κ light chain 3+ and λ light chain 1+, located within the intracapillary thrombi and in the capillary walls (× 400). (i-l) Micrographs of electron microscopy showing orderly arranged microtubular structures of 20–35 nm in diameter within the subendothelial and mesangial areas (× 5000)
