The World Health Organization (WHO) defines intracholecystic papillary neoplasms (ICPNs) as gallbladder lesions of intraductal papillary neoplasms of the bile duct (IPNB). We present a case of ICPN that was incidentally diagnosed following a cholecystectomy for cholecystitis and cholelithiasis. Abdominal ultrasonography and computed tomography showed thickening of the gallbladder wall and cholelithiasis but were not specific for a gallbladder tumor. Histopathological examination revealed an intracholecystic papillary-tubular neoplasm associated with a moderately differentiated adenocarcinoma.J Curr Surg. 2021;11(2):35-38doi: https://doi.org/10.14740/jcs408
