case_images: Light microscopy of renal biopsies stained with hematoxylin and eosin and showing bile casts with sclerotic glomeruli. Mild interstitial fibrosis and tubular atrophy are present, involving 10% of the cortical surface (grade 1 IFTA). Intratubular green-tinged casts (blue arrow) are present. Green pigment is also seen within the proximal tubular epithelium cytoplasm (black arrow). IFTA, interstitial fibrosis and tubular atrophy.
