Intraductal tubular papillary neoplasm (ITPN), a novel entity of pancreatic epithelial neoplasms and precursor of cancer: A case report and review of the literature.

•Intraductal tubular papillary neoplasm (ITPN) displays a very rare subtype of epithelial neoplasms of the pancreas.•To date, little is known about ITPN and particularly about pancreatic cancer arising in this tumor entity.•ITPN reveals a potential of malignant transformation. Radical surgical resection and oncologic follow-up is warranted.•When compared to ductal adenocarcinoma, patients with ITPN reveal less lymph node metastasis and a better overall survival.
