Severe acute kidney injury due to oxalate crystal induced severe interstitial nephritis: A case report

Figure 1 Oedema and marked diffuse mononuclear tubulointerstitial inflammation. The tubules had simplified epithelium with a lost brush border and reactive nuclear changes. There was no significant tubular vacuolization. The glomeruli appeared spared.

Figure 2  There is necrotic debris in two tubular lumens (lower left and upper right) and in the inspissated Tamm-Horsfall protein (center) on a severe inflammatory background.

Figure 3 The background is inflammatory and there is an oxalate crystal in the center-right. Necrotic debris in 2-3 tubules.
