Successful treatment of multiple hepatocellular adenomas with percutaneous radiofrequency ablation

Figure 2 The histological features are consistent with the inflammatory type of hepatocellular adenoma. A: A hepatocellular adenoma in GSD-Ia has several unpaired arteries (thick black arrows), sinusoidal dilation (thin black arrows), and steatosis (white arrows), but the atypia of hepatocytes are low without a nuclear pleomorphism; B: A reticulin staining does not show thick hepatic cords; C: The lymphocytic infiltrates are found in a hepatic lobule; D: The lymphocytes infiltrate in the area surrounded a portal and a periportal tracts; E: Staining for glutamine synthetase is diffuse cytoplasmic with focal nuclear expression; F: β-catenin staining does not show abnormal expression. GSD-Ia: Glycogen storage disease type Ia.
