Histopathology and immunohistochemistry findings. Hepatocellular cells with poor atypia proliferated diffusely in the tumor (a) H&E staining (magnification, 200 ×). Immunohistochemical analysis shows positive β-catenin in the cellular membrane and negative in the nucleus (magnification, 200 ×) (b), diffuse GS (magnification, 200 ×) (c), LFABP is positive (magnification, 200 ×) (d), SAA is negative (magnification, 200 ×) (e), and CRP is negative (magnification, 200 ×) (f). H&E stain, hematoxylin and eosin staining; GS, glutamine synthase; LFABP, liver fatty acid-binding protein; SAA, serum amyloid A; CRP, C-reactive protein
