	Histological abnormalities
Gross	LM: single fragmented core measured ∼0.8 cm EM: single core measured 0.8 cm
Light microscopy	Sections examined revealed corticomedullary renal tissue core containing 10 glomeruli.  • 7/10 glomeruli are globally sclerosed with periglomerular fibrosis  • 3/10 of glomeruli show segmental sclerosis  • Marked tubular atrophy is seen together with intraluminal hyaline casts; some tubules are dilated  • Severe mixed tubulointerstitial inflammation and fibrosis were found  • Thick-walled blood vessels are noted
Immunostaining	• lgG, lgM, lgA: focal mesangial (1+)
