Overview
Pathophysiology
Acute tubular necrosis from ethylene glycol
Histopathology: Toxic ATN is characterized by proximal tubular epithelium necrosis (no nuclei, intense eosinophilic homogeneous cytoplasm, but preserved shape) due to a toxic substance (poisons, organic solvents, drugs, heavy metals). Necrotic cells fall into the tubule lumen, obliterating it, and determining acute renal failure. Basement membrane is intact, so the tubular epithelium regeneration is possible. Glomeruli are not affected.
