Immunohistochemical staining of the tumor cells in the UESL showed strong positivity for vimentin (a) and α1-antitrypsin (b), patchy positivity for desmin (c), and negative for myogenin (d), smooth muscle actin (SMA) (e), and pancytokeratin AE1/AE3 (f). The entrapped hepatic cords were negative for AE1/AE3 (f) (arrowhead), but AE1/AE3 highlighted the entrapped bile ducts (f) (arrow) (immunoperoxidase; original magnification: ×200).
