Objective To analyze the clinical features of primary duodenal malignant tumor (PDMT). Methods The clinical data of 48 cases of PDMT confirmed by surgery and pathology from January 1974 to June 1999 in our hospital were summarized. Including the location, extent and pathological type of the tumor, the endoscopic and X-ray findings were analyzed, and the reasons for missed diagnosis and misdiagnosis were discussed. Results PDMT accounted for 0.41% of gastrointestinal malignant tumors during the same period; more men than women; abdominal pain, bleeding, and vomiting as the main clinical manifestations; PDMT occurred in the descending segment accounted for 6475%, with the most common adenocarcinoma (79% Diagnostic endoscopy, X-ray barium meal as the main means, surgical treatment is the preferred treatment. Conclusion The vigilance to PDMT should be enhanced, and improving the early diagnosis rate is the key to improve the prognosis
