Figure 5. Autopsy findings. (A) Macroscopic findings in the pancreas showing a 4-cm-diameter mass lesion expanding from the pancreatic head to the body (arrows). (B) Histopathological examination of the mass lesion showing proliferation of polymorphic malignant cells with circular- to spindle-shaped nuclei with large and small disparities in diameter (hematoxylin and eosin staining; original magnification ×400). (C) Macroscopic findings in the liver showing extension of the tumor mainly through the intrahepatic portal veins (arrows). (D) Histopathological examination of the liver showing infiltration of the same malignant cells in the intrahepatic portal vein (arrow) and in the liver parenchyma (arrowhead) (hematoxylin and eosin staining; original magnification ×100).
