Introduction. Intracholecystic papillary neoplasia is characterized by exophytic growth of the gallbladder epithelium into its interior. Clinical cases. We present two clinical cases with a gallbladder mass that underwent cholecystectomy given the risk of being malignant gallbladder polyps. The pathological anatomy certifies that they correspond to an intracholecystic papillary neoplasia. Discussion. Intracholecystic papillary neoplasia is a rare pathology, whose incidence varies from 0.5 to 0.8%, predominates in females and affects patients with a mean age of 60 years. Macroscopically it appears as a gallbladder polyp. It is a lesion with potential risk of malignancy which is why it is considered a precursor lesion for the development of invasive gallbladder carcinoma. It is important to note that intracholecystic papillary neoplasia that progresses to invasive carcinoma has a better prognosis than gallbladder carcinoma that originates from another type of lesion. Conclusion. The presence of an exophytic growth lesion at the gallbladder level should make us suspect intracholecystic papillary neoplasia, being recommended to perform cholecystectomy.
