A 39‐year‐old male with general malaise visited our clinic with high levels of aminotransferases (AST 776 IU/1, ALT 1,069 IU/I) and a prolonged prothrombin time. Serum‐fetoprotein (AFP) level was markedly elevated (2,214 ng/ml) and human hepatocyte growth factor (hHGF)was also high (0.81 ng/ml). Hepatocellular carcinoma was found to be negative from imaging techniques. AFP bands separated by lectin affinity electrophoresis had a benign pattern. Laparoscopic diagnosis was scarred liver and histologically massive hepatic necrosis with a strongly positive AFP stain. Levels of hHGF and AFP fell into a normal range after treatments with glucagon‐insulin and prostaglandin Ei. At second laparoscopy, regenerated nodules were confirmed by improved staining with Indocyanine Green. Hepatocyte regeneration was also histologically proven with a weakly positive AFP stain. The proliferating cell nuclear antigen (PCNA) was stained, and hepatocytes with PCNA positive nuclei were not seen at the time of the first laparoscopy, whereas hepatocytes with PCNA positive nuclei were found to be many at the time of the second laparoscopy. Seroconversion from HBe Ag to HBe Ab was observed 4 months after the maximum rise of AFP (6,341 ng/ml), when levels of ALT and DNA polymerase were within normal ranges. This is a patient with a marked rise in his serum level of AFP in association with seroconversion from HBe Ag to HBe Ab, and the elevation of AFP in the present case was thought to reflect severe liver injury with concomitant regenerative activities of injured hepatocytes rather than simple hepatocyte regeneration after hepatic necrosis was resolved.
