Mucin Hypersecreting Intraductal PapillaryNeoplasm of the Pancreas

摘要

Mucin Hypersecreting Intraductal Papillary Neoplasmis a rare neoplasm that arises from ductalepithelial cells. This entity is distinct from the morecommonly known Mucinous Cystadenoma or MucinousCystadenocarcinoma. Despite this distinction,it has been erroneously categorized with thesemore common cystic neoplasms. Characteristic clinicalpresentation, radiographic, and endoscopicfindings help distinguish this neoplasm from thecystadenomas and cystadenocarcinomas. Histopathologicidentification is not crucial to thepreoperative diagnosis. This neoplasm is consideredto represent a premalignant condition and, therefore,surgical resection is warranted. Prognosis,following resection, is felt to be curative for themajority of patients.We present two cases of Mucin HypersecretingIntraductal Papillary Neoplasm and discuss theirdiagnosis and surgical therapy.
