Benign duodenal tumor

Benign tumors of the duodenum are less common than malignant tumors, with a benign-to-malignant ratio of 1:2.6 to 1:6.8. Although duodenal benign tumors are themselves benign, some have a high tendency for malignant transformation, and some are inherently borderline between benign and malignant, even difficult to distinguish under the microscope. In particular, the location of tumor growth is often closely related to the biliary and pancreatic drainage systems, the position is fixed, and the duodenal lumen is relatively narrow, so they often cause various symptoms and may even lead to serious complications that threaten life. Due to the special location of the duodenum, surgical management of these tumors is very difficult.
