Background: Intracholecystic papillary neoplasms (ICPNs) represent a rare benign entity characterized by intraluminal polypoid lesions in the gallbladder. The incidence of ICPNs ranges from 0.4% to 0.61% in all gallbladder specimens.
Case presentation: In this report, we present a case of a young Caucasian woman who underwent elective laparoscopic cholecystectomy due to gallbladder polyps. The histological examination revealed the presence of an intracholecystic papillary neoplasm (ICPN) with a tubulopapillary growth pattern, exhibiting gastric morphology and displaying both low and high-grade dysplasia. A thorough review of the existing literature was conducted, with a specific focus on the histological features.
Conclusion: A comprehensive understanding of neoplastic polyps of the gallbladder is still limited. Pathological examination of these lesions is crucial for identifying key features that can influence patient outcomes and survival.
