Resumen

Introduction: Gallbladder adenomyomatosis (GAM) is a benign condition of the gallbladder, typically asymptomatic, but with the potential to mimic or coexist with preneoplastic lesions. Clinical case: We report seven cases of GAM, incidentally discovered following cholecystectomies performed due to right upper quadrant pain. All patients were adults (six women and one man), with a preoperative diagnosis of cholecystitis or cholelithiasis, and no abnormalities in laboratory studies. The lesions were located in the gallbladder fundus, with thicknesses ranging from 2 to 12 mm. Histopathological analysis revealed typical features of GAM, and in one case, a single focus of low- and high-grade glandular dysplasia was identified, without evidence of invasion. Conclusion: The significance of this case lies in the need for thorough histological examination of the gallbladder, even when there is no clinical suspicion, due to the oncogenic potential of the dysplasia associated with GAM and the importance of differential diagnosis with gallbladder neoplasms.
