Concomitant hepatocellular adenoma and adenomatous hyperplasia in a patient without cirrhosis

Figure 1 A hypoechoic lesion in the right lobe of the liver, segment S6, 24 × 22 mm in diameter (asterisks).

Figure 2 No evidence of hepatocellular tumor seen on upper abdominal CT with contrast.

Figure 3 On angiography, there was an oval hypervascular lesion (black arrows) and multiple scattered tiny hypervascular spots in the right lobe of the liver (white arrows).

Figure 4 Slightly disarrayed hepatocytes with nuclear dyspla-sia were found. Besides one-to-two layer reticulin stain, not consistent with HCC, was present. (Reticulin stain, × 250).

Figure 5 An oval-shape nodule (black arrows) which consisted of disarrayed hepatocytes with nuclear change and clear change in the cytoplasm was surrounded by normal liver tissue. (H&E stain, × 125).
