Acute Interstitial Nephritis

The images show lymphocytic tubulitis as well as an eosinophil-rich interstitial inflammatory infiltrate. These findings are consistent with acute interstitial nephritis. The eosinophil-rich nature of the infiltrate is compatible with a drug/hypersensitivity reaction which was present in this patient, occurring from recent antibiotics exposure with subsequent acute renal failure and development of a rash.
