Abstract
A 39-year-old woman developed anemia and tarry stools. She was diagnosed as having gastrointestinal bleeding and an intussusception along with a duodenal tumor based on abdominal CT scans, a small bowel series, and small bowel endoscopy. The patient had no abdominal pain or symptoms of intestinal obstruction. She underwent elective laparotomy. Intraoperative endoscopy revealed that the tumor (7 cm in diameter) was pedunculated and located on the opposite side of the papilla of Vater in the duodenal bulb. The tumor was diagnosed as an inflammatory fibroid polyp (IFP) on the intra-operative pathology of an open biopsy. Consequently, a duodenectomy was performed. On postoperative pathology, a proliferation of spindle-shaped cells which lacked atypia and chronic inflammation were noted. Therefore, the tumor was diagnosed as a duodenal IFP. The characteristics reported in the literature of patients with this rare duodenal IFP are also presented in this paper.
