title: Xanthogranulomatous cholecystitis.
abstract: Clinical, radiological and pathological findings in 31 patients with xanthogranulomatous cholecystitis have been reviewed. The spectrum of presentation was similar to that of cholelithiasis but fewer patients had biliary colic (17 per cent) and there were more complications (32 per cent). Four patients had a biliary fistula and four a perforated gallbladder with abscess formation. Patients characteristically had gallstones. Appearances often mimicked carcinoma of the gallbladder at ultrasonography and/or laparotomy, with xanthogranulomatous tissue extending to adjacent structures. Xanthogranulomatous cholecystitis and carcinoma of the gallbladder coexisted in three patients. The possibility should be considered that an 'inoperable tumour' of the gallbladder may in fact be xanthogranulomatous cholecystitis, a benign condition that frozen-section biopsy may confirm.
