title: Xanthogranulomatous cholecystitis. A clinical and pathologic study of twelve cases.
abstract: Xanthogranulomatous cholecystitis often presents as a severe chronic cholecystitis associated with abdominal pain, fever, and leukocytosis. Gallstones are present in most cases. At operation, there are adhesions to surrounding tissues, and sometimes a mass is found, mimicking tumor of the gallbladder. The gross and microscopic appearances are characteristic with multiple intramural nodules composed of foamy histiocytes and inflammatory cells. Cholesterol contents of these nodules are high. Involvement of the Rokitansky-Aschoff sinuses with liberation of bile lipids into the adjacent tissue is implicated in the pathogenesis of this lesion.
