Pathological findings of the episode biopsy (third biopsy). a-1 Glomerulus showed hyper-cellularity and mesangial interposition was observed. a-2 High magnification of black-boxed area in a-1. The arrow shows duplication of the glomerular basement membrane. b Glomerular immunofluorescent staining (original magnification, ×100). b-1 Global mesangial and capillary granular deposits of C3c. b-2 No apparent IgG deposition. b-3 No apparent IgA deposition. b-4 Segmental IgM deposition. b-5 No apparent C1q deposition. c-1 Subendothelial deposits (arrow) were observed on electron microscopy (original magnification, ×3000). c-2 Subendothelial deposits (arrow) were observed on electron microscopy (original magnification, ×8000)
