Abstract
An 85-year-old woman was presented to our center with a right lower abdominal pain and a mass. Abdominal computed tomography showed multiple cystic lesions adjacent to the gallbladder. The patient underwent cholecystectomy with ascending colectomy and the intraoperative findings were suggestive of a gallbladder carcinoma invaded to the ascending colon. The pathological findings after surgical resection revealed a moderately differentiated tubular adenocarcinoma at cystic regions and xanthogranulomatous cholecystitis (XGC) at the fundus of the gallbladder. Although invasion to the colon was suspected intraoperatively, only inflammation of XGC was affected to the colon. This case was an unusual case is described in which a gallbladder carcinoma was complicated with XGC and formed a lower abdominal mass.
