(a) The tumor cells show papillary growth pattern and nuclear palisading around fibrovascular cores (HE stain, original magnification ×400). (b) The tumor cells show positive immunoreactivity for bcl-2 (Immunohistochemistry, original magnification ×400). (c) A few tumor cells weakly show positive immunoreactivity for p53 (Immunohistochemistry, original magnification ×400). (d) A few tumor cells show positive immunoreactivity for Ki-67 (Immunohistochemistry, original magnification ×400).
