title: [A Case of Undifferentiated Carcinoma of the Gallbladder].
abstract: In this paper, we present a case of undifferentiated carcinoma of the gallbladder, which is a rare disease with poor prognosis. A 77-year-old woman presented with right hypochondralgia. An abdominal CT scan showed a tumor more than 80 mm in diameter invading the liver parenchyma and transverse colon, and showed liver and lymph node metastases. We diagnosed the patient with stage Ⅳ carcinoma of the gallbladder. We resected the gallbladder, S4a plus S5 of the liver, part of the transverse colon, the lymph nodes, the greater omentum, and the extra hepatic bile duct; biliary reconstruction was then performed. Histological examination showed that most areas consisted of undifferentiated cells. The diagnosis of undifferentiated carcinoma was made according to the WHO classification of tumors of the digestive system. No recurrence has been detected for 1 year.
