title: Renal malacoplakia with secondary hepato-duodenal involvement.
abstract: Renal parenchymal malacoplakia is uncommon, and coexistence of extensive invasion into the liver and duodenum is extremely rare. Typically, there is an associated long-term urinary tract infection. We report on a 53-year-old woman with a history of diabetes and recurring pyelonephritis, who presented with a renal tumor and upper gastrointestinal bleeding. Surgical intervention included radical nephrectomy, lymphadenectomy, segmental hepatectomy, cholecystostomy, duodenorrhaphy, jejunostomy and appendectomy. There was no surgical morbidity. A pathologist confirmed the diagnosis of malacoplakia. All of the diagnostic criteria, including hematoxylin and eosin stain, iron stain, calcium stain and electron microscopy of Michaelis-Gutmann bodies, were classic. The literature is reviewed.
