Abstract:
Intracholecystic papillary neoplasm (ICPN) of the gallbladder is a rare tumor described as a mucosal exophytic neoplastic lesion that projects into the gallbladder lumen. In regards to the size, lesions that did not make the arbitrary 1cm cutoff are described as "incipient" ICPN. Not much is known about these incipient ICPNs, as they are often excluded in ICPN studies, given the attempted adherence to the traditional 1cm cutoff. We present the youngest reported case of incipient, non-mucinous gastric-pylorus type ICPN who underwent cholecystectomy. Resection with negative margin for ICPN appears to be sufficient treatment and post resection imaging surveillance could be of value but further studies are required.
