Neoplastic Disorder

Pancreatic Intraductal Neoplasms

EPITHELIAL NEOPLASMS with pancreatic ductal differentiation that arise from the EXOCRINE PANCREAS and grow mostly within the PANCREATIC DUCTS. They are characterized by the presence of intraductal masses with mostly papillary growth pattern. Overt production of MUCIN within the pancreatic duct is associated with pancreatic intraductal papillary-mucinous neoplasm but not intraductal tubulopapillary neoplasm.
