Acute tubular injury and immune cell infiltration in coronavirus disease 2019 kidneys. (A) The renal cortex on light microscopy shows acute tubular injury with lumina ectasia (hematoxylin and eosin [HE] stain, original magnification ×20). (B) Mild mononuclear interstitial infiltration and peritubular capillary congestion is noted (HE stain, original magnification ×40). (C and D) Peritubular capillaritis (arrow) is a notable feature within congested capillaries (C). The microvascular inflammation is composed of CD3-positive T cells (E) and CD68-positive macrophages (F) (original magnification ×40 for E and F).
