Adenomyomatous hyperplasia and adenomyoma are rare benign inflammatory pseudotumors of the gallbladder arising from Rokitansky-Aschoff sinuses. Occurrence of these hyperplastic conditions in the Vaterian and biliary system is extremely rare and is a concern for gastroenterologists and surgeons in distinguishing them from primary malignancies of the biliary system. Definitive diagnosis by imaging or cytopathological examination is difficult; thus, surgical resection becomes the only choice in such cases to relieve the obstruction.

Background: The relationship between adenomyomatous hyperplasia of the Vaterian system(AV) and cancer is unclear, some reports suggest that AV is often combined with mucosal glandular dysplasia, but it is not clear whether mucosal glandular dysplasia is a risk factor for carcinogenesis of AV. The aim of this study was to retrospective analysis of role of ductal glandular dysplasia as a risk factor in the development of carcinoma in AV.
Methods: A total of 328 cases who underwent surgery with a final pathological diagnosis of adenomyomatous hyperplasia (AH) in the Chinese PLA General Hospital in BeiJing, China, between January 2005 and December 2021 were retrospectively collected.
