Abstract
A 75-year-old man who had a history of rupture of primary liver cancer was admitted to Kanmon Medical Center with severe anemia (Hb 3. 0 g/dl). A bleeding ulcerative tumor (ulcerated type with clear margin (Type2) ) was found by esophagogastroduodenoscopic examination. The tumor was located from duodenal bulb to duodenal 2nd portion. Direct invasion of the primary liver cancer to the duodenum was suspected by specimen biopsy and abdominal CT. Invasion of the primary liver cancer to the duodenum is relatively rare (1%) among metastasis of primary liver cancer to other organs. In this paper, we report a rare case of this primary liver cancer invading into duodenum directly.
