Abstract:
Lysozyme-induced nephropathy is a rare form of acute tubular injury that has almost exclusively been reported in patients with monocytic malignancies. Typically, patients will present in acute renal failure A renal biopsy is necessary to confirm the diagnosis and will demonstrate proximal tubular cells with hypereosinophilic granules, which are periodic acid-Schiff and Jones methenamine silver-positive. Immunohistochemical staining for lysozyme will also be present. The following rare case will describe a case of lysozyme nephropathy in a patient without any underlying hematological malignancy, but instead with systemic granulomatous disease.
