A case of liver tumor in a 54-year-old woman is presented. She has no history of use of oral contraceptives. She was admitted because of a space-occupying lesion of the liver. Anemia and jaundice were not found on physical examination. Alphafetoprotein was within normal limits. A tumor mass 3 cm in diameter was detected in the right lobe of the liver by ultrasonography and computed tomography (CT). Angiographic hypervascularity suggested a diagnosis of hepatocellular carcinoma, but the absence of accumulation in the lipiodol CT and slight tumor stain in the trans SMA (supra-mesentric artery) portal CT did not support it. Partial hepatectomy and cholecystectomy were performed. The tumor was soft and greenish brown measured 3.2 × 2.2 × 3.7 cm and was sharply demarcated. Histologically, proliferation of enlarged hepatocytes rich in glycogen and with abundant lipochrome was seen. Tumor cells were arranged slightly irregularly. Bile duct tissues were not found in the tumor and the final diagnosis was liver cell adenoma. Chronic hepatitis without liver cirrhosis was found in her background.
