case_images: Magnetic resonance imaging characteristics and liver biopsy histopathology. (A) Axial view from enhanced abdominal magnetic resonance imaging revealed a liver mass located in the right lobe without typical enhancement. (B) Hematein eosin stain composed of a small amount of abnormal mitotic cells, lacking the portal triads or bile ducts (original magnification x 200). (C) Immunohistochemical showed beta-catenin was positive on membrane, not nuclei (original magnification x 200). (D) The radiology images showed that the mass shrank significantly.

case_images: F1
case_images: T2 with a range of 65.0 x 45.0 mm, and normal liver contour with no signs of liver cirrhosis. The mass was enhanced in the arterial phase and persisted in the portal venous and hepatobiliary phases (Figure 1A). Immunohistochemical staining showed that beta-catenin was positive on the membranes, with < 10% positive for Ki67, consistent with a hepatic adenoma (Figures 1B,C). In the meantime, we excluded the extramedullary hematopoietic foci as no characteristic signs were found via microscopy. The lesion diminished gradually over a two-year follow-up (Figure 1D).
