Many studies have identified three preinvasive
lesions of pancreatic cancer: pancreatic intraepithelial neoplasia (PanIN), intraductal papillary mucinous neoplasms (IPMN), and mucinous cystic neoplasms (MCN), among which pancreatic intraepithelial neoplasia lesions are the most common and most well characterized.
21) The progressive accumulation of molecular alterations in support of a preinvasive
carcinoma has led some authors to prefer the term medullary carcinoma in situ or C-cell dysplasia over neoplastic CCH because it better reflects its true biologic nature.
