I agree with all above. The lesion has mucinous adenocarcinoma component.
One important question needs to answer: what is the relationship between the lesion with pancreatic duct? If the lesion is associated/linked with main pancreatic duct, it is possible that this represents an invasive mucinous adenocarcinoma arising in a background of IPMN and extending to common bile duct. Photos 6 and 8 seem to have intraductal neoplasm component.
Clinical correlation, including imaging correlation, is helpful.
IPMN with invasive mucinous adenocarcinoma has a better progress than classic mucinous adenocarcinoma.
