Core Tip

Core Tip: This case report presents a case with an isolated liver metastasis 11 years after surgery for rectal cancer. In addition, it is difficult to differentiate a late liver metastasis of colorectal cancer (CRC) from intrahepatic cholangiocarcinoma (ICC) preoperatively. We should note the possibility that a liver tumor in a patient with a history of curatively resected CRC might not be ICC nor hepatocellular carcinoma but metastasis from CRC, even if CRC was diagnosed and resected more than 10 years earlier.
