Figure 1 Clinical data and cell morphology. A: Clinical data of the patient; B: Magnetic resonance cholangiopancreatography shows the expansion of intrahepatic and extrahepatic bile ducts, gallbladder enlargement, and pancreatic duct expansion (arrow); C: In the coronal view of magnetic resonance imaging, soft tissue shadow (arrow) can be seen in the ampulla, and the upper bile duct is dilated; D: General view of the surgical specimen; E: The enlarged appearance of the ampulla tumor shows the gray-white tumor growing around the ampulla (arrow); F: DPC-X1 primary cell morphology; multinucleated cells and megakaryocytes can be seen; G: DPC-X1 cell morphology of the 80^th generation. Scale bars: 100 μm. D: Death; AFP: alpha-fetoprotein; CEA: Carcinoembryonic antigen; CA199: Carbohydrate antigen 199.
