case_images: Light microscopy (A - C) and electron microscopy (D) pictures of a renal biopsy specimen. A: PAS stain showing glomerular tuft collapse and overlying epithelial hyperplasia. B: Jones' silver stain showing glomerular tuft collapse and overlying epithelial hyperplasia. C: Light microscopy showing acute tubular injury. D: Electron microscopy showing diffuse podocyte foot process effacement.

case_images: Kidney biopsy was consistent with collapsing glomerulopathy with evidence of tubular injury, moderate interstitial fibrosis, and tubular atrophy but no pathologic evidence of thrombotic microangiopathy (Figure 1).
