Combined Xanthogranulomatous Urachitis and Bullous Cystitis: A Case Report.: Ji Eun Kwak, Han Seong Kim, Mee Joo, Sun Hee Chang, Sang Hwa Shim, Je G Chi, In Rae Cho; Korean J Pathol. 2008;42(1):41-44.

Abstract PDF: Xanthogranulomatous inflammation of the urachus is a very rare benign chronic inflammatory disease of an unknown etiology. Herein we report a case of a 31-year-old woman who complained of lower abdominal pain and dysuria. Cystoscopy revealed a bullous change at the dome of the urinary bladder. MRI revealed a cystic mass above the bladder dome that extended to the umbilicus. A partial cystectomy with urachal resection was performed. Pathological examination revealed xanthogranulomatous urachitis combined with bullous cystitis.

Abstract PDF: Xanthogranulomatous cholecystitis is a rare form of inflammatory disease of the gall bladder and was first described in 1970 by Christensen and Ishak as fibroxanthogranulomatous inflammation of the gall bladder. Recently authors experienced three cases of xanthogranulomatous cholecystitis, two of which were erroneously diagnosed as malignant tumor in preoperative clinical and radiological examinations. Grossly, the gallbladders were enlarged and the walls were thickened with yellowish granular necrotic areas ranging from a few millimeters to 1.0 cm in diameter. Microscopically, all of three cases showed diffuse infiltration of the foamy histiocytes containing bile pigments and mononuclear leukocytes associated with fibroblastic proliferation and foreign body reactions. The pathogenesis of the xanthogranulomatous cholecystitis is uncertain, but opinion favours an inflammatory response to extravasated bile probably, from ruptured Rokitanky-Aschoff sinuses. Three cases of xanthogranulomatous cholecystitis with brief review of literature are presented.
