A 45year old man, who had been taking large doses of paracetamol to treat a cold, developed oliguria and azotemia. 5 days later he died with signs of acute renal failure. Renal histology shows diffuse edema of the medullary interestitium infiltrated with lymphocytes, eosinophils, and single neutrophils: renal tubular epithelium is destroyed; glomerular changes are mild. What is the most likely type of kidney damage in this case?
