Incidental gallbladder cancer originating from cholecystic adenomyosis: a report of five cases / 中华肝胆外科杂志

Cholecystic adenomyosis is a common benign lesion of the biliary system. Recently, cholecystic adenomyosis has been diagnosed to harbour an incidental gallbladder cancer (IGBC) on intraoperative or postoperative pathological examinations. In this article, we reviewed 586 patients who were treated at Zhongshan Hospital, Fudan University with a preoperative diagnosis of cholecystic adenomyosis, and found 5 patients with IGBC diagnosed by pathological examinations. We described the clinical characteristics, imaging features and pathological findings of these 5 cases. We further reviewed the relevant medical literatures to provide a comprehensive view on IGBC of adenomyosis origin.
