Resection for hepatocellular carcinoma with duodenal invasion: report of a case.

A 73-year-old man was admitted to our hospital on emergency for severe anemia. Upper gastrointestinal endoscopic study revealed a hemorrhagic ulcer in the duodenal bulb. He underwent endoscopic hemostasis. Abdominal ultrasonography and computed tomography showed a huge mass in segment 4 of the liver, growing into the extrahepatic space with direct invasion to the duodenal bulb. Extended left lobectomy and partial gastroduodenectomy was performed, because the endoscopic management of hemostasis was incomplete. He was discharged on the 30th postoperative day. Histopathologically, the tumor cells were moderately differentiated hepatocellular carcinoma with direct invasion to the duodenal mucosa. This report demonstrated the first case with a hepatocellular carcinoma with duodenal invasion, for which hepatic resection was performed successfully.
