A Case of Resected Cholangiolocellular Carcinomaduring Treatment for Lung Cancer

A Case of Resected Cholangiolocellular Carcinoma during Treatment for Lung Cancer Cholangiolocellular carcinoma is an extremely rare malignant primary liver tumor, accounting for less than 1% of primary liver tumors. We herein report a case of cholangiolocellular carcinoma during treatment for lung cancer. A woman following up after operation for lung cancer was found to have a solitary hepatic tumor in the left lobe of the liver at an abdominal computed tomography checkup. It showed early enhancement with hypovascular area of the center in the arterial phase and enhancement contrast retention in the delayed phase. The tumor was seen as a hypointense nodule in the hepatocellular phase of EOB magnetic resonance imaging. We diagnosed liver metastasis of lung cancer with differential diagnosis of cholangiocellular carcinoma. We performed extended left lobectomy of the liver. Histological and immunohistochemistry findings were compatible with cholangiolocellular carcinoma./p>
