Intraductal Tubulopapillary Neoplasm: A New Entity in the Spectrum of Pancreatic Intraductal Neoplasms

Intraductal Tubulopapillary Neoplasms (ITPN) is a rare and new entity defined as an intraductal, grossly visible, tubule-forming epithelial neoplasm with high- grade dysplasia and ductal differentiation without overt production of mucin. Its clinical presentation can be varied, which makes the diagnosis quite challenging. In this report, we present a case of pancreatic ITPN and review the published work to learn clinicopathological, radiological features and treatment strategies of this recently proposed pancreatic neoplasm.
