Abstract
- Malacoplakia is a rare, chronic inflammatory disorder characterized by abnormal macrophage function and cell infiltration into normal tissues. We report a 72 year old male with bilateral renal parenchymal malacoplakia who presented with high fever and acute renal failure. The patient had anemia, leukocytosis, thrombocytopenia and bilateral nephromegaly with reduced renal function. Blood and urine cultures showed no micro-organisms. A kidney biopsy revealed diffuse interstitial histiocytic infiltration with intracellular inclusion bodies(Michaelis-Gutmann body). He was treated with antibiotics, and bethanechol, ascorbic acid without improvement. Following treatment with an intravenous methylprednisolone pulse therapy, clinical improvement was made. Renal parenchymal malacoplakia should be considered in the differential diagnosis when presented with high fever, enlarged kidneys and acute renal failure.
