Abstract
A 77-year-old woman was admitted with the complaint of epigastralgia and was diagnosed as cholangitis as a result of stones in the common bile duct. Abdominal ultrasonography and computed tomography revealed an irregular tumor in the gallbladder. We diagnosed this as carcinoma of the gallbladder and performed cholecystectomy. Macroscopic examination of the resected specimen showed a papillary tumor growing from the fundus and body of the gallbladder.
Histologically, the resected specimen consisted of an adenocarcinoma and a sarcomatous tumor of spindle-shaped cells and we diagnosed this case as carcinosarcoma of the gallbladder. Carcinosarcoma of the gallbladder is very rare, so we report this case with a review of the literature.
