A 61-year-old woman was referred for mild biliary and pancreatic duct ectasia on MRI.

EUS revealed a 12 mm, isoechoic, intraductal pancreatic head lesion. ERCP-pancreatoscopy showed a polypoid lesión suggesting intraductal papillary mucinous neoplasm (IPMN).

Final histopathology of surgical specimen (duodenopancreatectomy) revealed an uncommon entity: Intraductal tubulopapillary neoplasm (ITPN).

ITPN is a subtype of premalignant pancreatic neoplasms, distinct from IPMN. ITPN show tubulopapillary growth, cuboidal to columnar and scarce mucin. Immunohistochemical studies may also be distinctive.

ITPN has a more favorable prognosis. The role of EUS and pancreatoscopy has to be determined but might potentially help in preoperative diagnosis.
