Computed tomography (CT) images before living-donor liver transplantation and histopathological findings of the resected native liver. a Preoperative abdominal CT showing liver cirrhosis with three hypervascular nodules that were 20, 25, and 28 mm in diameter. Embolism deposits due to transarterial chemoembolization (TACE) were observed in one of the three S1 tumors. b Macroscopic examination of the resected liver revealed the presence of a tumor 28 mm in diameter with partial necrosis due to preoperative TACE in segment 1, but no tumors were observed in other areas, only regenerated nodules. c, d Microscopic view of moderately differentiated hepatocellular carcinoma (HCC) with necrotic changes in segment 1 and multiple well-differentiated HCC lesions with trabecular and pseudoglandular structures measuring a few millimeters in diameter
