Case report: A Case of low-grade appendiceal mucinous neoplasms combined with incidental gallbladder cancer

Abstract Mucinous tumors of the appendix are relatively rare compared to other gastrointestinal tumors, but their incidence tends to gradually increase. Due to the lack of specific clinical manifestations, mucinous tumors of the appendix are prone to misdiagnosis and missed diagnosis. According to different pathological types, mucinous tumors of the appendix can be roughly divided into low-grade mucinous tumors and high-grade mucinous tumors, with significant differences in prognosis. Gallbladder cancer is the most common type of malignant tumor in the biliary system, with a high degree of malignancy, poor prognosis, and consistently high mortality rate. With the widespread promotion of laparoscopic technology, an increasing number of gallbladder cancers are accidentally discovered after laparoscopic cholecystectomy, indicating an upward trend in incidental gallbladder cancer. This article provides a detailed report on a case of low-grade appendiceal mucinous neoplasms combined with incidental gallbladder cancer.
