Duodenal Adenocarcinoma with Multiple Metastases from Intestinal Tumors

Abstract

A 71-year-old man suffering from epigatralgia and anorexia, was found to have anemia and a hyperactive inflammatory response. Abdominal enhanced CT showed a tumor at the duodenal bulb. A type 2 tumor was found at the anterior wall of the duodenal bulb, and biopsy revealed adenocarcinoma. Intraoperative findings revealed 5 tumors at the upper jejunum, and 2 at the end of the ileum. A gastrojejunum bypass procedure and resection of the ileum was performed to prevent exacerbation of anemia. Immunohistochemical examination revealed that the duodenal tumor was primary and the intestinal tumors were metastatic. Duodenal adenocarcinoma with multiple metastatic intestinal tumors are very rare.
