[A Case of Slow-Growing Intrahepatic Cholangiocarcinoma after Resection of Gastric Cancer].

An 83-year-old woman was given a diagnosis of gastric cancer and received distal gastrectomy 9 years ago. Three years later, CT revealed a tumor measuring 13 mm in diameter in hepatic segment 7. She was followed for 5 years, and the size of the tumor did not change. Eight years later after gastrectomy, the tumor size slightly enlarged to 17 mm, and biopsy revealed adenocarcinoma. The patient underwent liver resection of segment 7. The pathological diagnosis was well differentiated intrahepatic cholangiocarcinoma(ICC). No sign of recurrence has been found during a 1-year. This case, in which the patient was followed for 5 years before curative surgical treatment, is significant, because it demonstrates the slow-growing nature of ICC.
