Abstract

Gallbladder polyps are frequently found on abdominal ultrasonography. Most gallbladder polyps are benign. However, the risk of malignancy increases when the polyp size exceeds 10 mm. The fifth edition of the World Health Organization Classification of tumors proposed three types of preinvasive neoplasms of the gallbladder: adenoma, intracholecystic papillary neoplasm (ICPN), and biliary intraepithelial neoplasia (BilIN). Herein, we report a case of a growing gallbladder polyp that was diagnosed with ICPN after cholecystectomy, along with a brief literature review.
