A case report of intracholecystic papillary neoplasm presenting as gallbladder polyp

Intracholecystic papillary neoplasm was a newly proposed term in the 2019 World Health Organization classification of tumors of the digestive system, as a preinvasive neoplasm of the gallbladder. We report a case of intra-cholecystic papillary neoplasm, biliary type with high-grade dysplasia presenting as a polypoidal mass in the fundus of the gallbladder, in a 47-year-old man with a history of periodic abdominal pain and dyspepsia of 6-month duration. As the term for the pathological classification in itself is new, we wish to report this case for record storing purposes that may be imperative if any further study on the said topic is planned in the future.
