Histopathologic findings of kidney biopsy. (A) Diffuse vacuolization of the proximal tubules with acute tubular injury (Periodic Acid–Schiff; original magnification ×100). (B) Large vacuoles in proximal tubular epithelial cells with flattened tubular epithelium and dilated tubular lumen (Periodic Acid–Schiff; original magnification ×400). (C) Electron microscopy reveals intracytoplasmic, electron-lucent vacuoles in the proximal tubular epithelial cells (original magnification ×2500). (D) With no lysine kinase (WNK) bodies in the distal tubular epithelial cell (red arrows; original magnification ×8000)
