A 35 year-old male patient admitted due to epigastric pain for 1 month. He was heavy drinker and spider angioma was obserbed in physical examination. HBsAb, anti-HBs Ab and anti-HCV Ab were all negative and AFP level was normal. AST/ALT were elevated to 178 IU/L and 107 IU/L, respectively. At ultrasonography, CT and MRI, a 2 cm, hypervascular mass was detected in the segment Ⅵ. Segmentectomy of the segment Ⅵ was performed. Tumor size 1.7 cm in maximum diameter and the Edmondson and Steiners grade Ⅰ. High-grade dysplasia was present in the periphery of hepatocellular carcinoma (nodule-in-nodule). Microvascular invasion was not observed and background liver was cirrhotic. He was discharged 10 days after operation without any problem and there has been no evidence of recurrence for the 2 years postoperatively.
A 47-year-old male was referred for evaluation of a hepatic nodular lesion incidentally found on routine check up. He had no history of previous liver disease. Physical examination revealed no abonormality. Laboratory findings showed that HBsAG and anti-HCV were negative. Serum AST was minimally elevated and serum AFP was within normal range. Abdominal ultrasonogram showed a 1.3 cm-sized, hypoechoic nodule with peripheral halo in segment 5 of liver. Spiral CT revealed a well enhancing nodule in arterial phase, which could not be detected in portal and delayed phase. Liver biopsy showed well-differenciated hepatocellular carcinoma on the background of high grade dysplastic nodule. Surgical resection was recommended, however he refused and discharged.
