The primary hepatocellular carcinoma. (A) Dynamic computed tomography revealed a 20-mm-diameter hypervascular mass in segment 7 and a 20-mm-diameter hypovascular mass in segment 8. (B, C) Gross appearance of the two resected hepatic tumors. (D, E) Microscopic examination of the two specimens revealed moderately differentiated HCC. A few of the HCC cells from segment 7 were poorly differentiated, and there was evidence of tumor invasion into the portal vein (H&E, ×20).
