Light microscopic features of the biopsy specimen: (a) low magnification and (b to d) high magnification images of the glomeruli. Infiltration of lymphocytes and plasma cells in the interstitium, severe interstitial fibrosis and tubular atrophy were observed (a). The glomeruli show global sclerosis (b), multiple adhesion to Bowman’s capsule (c: arrowheads), segmental sclerosis with increased matrix and adhesion (d: arrowheads) and occasional hyaline droplets in podocyte cell bodies (d: arrow). Periodic acid-Schiff stain. Scale bars: 30 μm
