Abstract
A 64-year-old woman with continuous abdominal pain was admitted to our hospital under a provisional diagnosis of intestinal obstruction. Abdominal X-ray examination showed a dilated small intestinal loop. Abdominal CT scanning indicated intussusception of the small intestine. An X-ray examination through a long intestinal decompressing tube indicated a tumor of the ileum but no sign of obstruction. We performed an elective operation. A tumor was observed at a point 140 cm oral from Bauhin's valve, and a partial resection of the ileum with the tumor was performed. The tumor was 2.8 cm in diameter, round, with a short stalk, and lacked mucosa on its superior surface. Histological findings showed proliferation of stromal tissues and inflammatory cells containing eosinophils. The tumor was diagnosed as an inflammatory fibroid polyp (IFP). The postoperative course was uneventful and the patient was discharged on postoperative day 9. IFP is a benign submucosal lesion of the gastrointestinal tract that rarely arises in the small intestine. Over 80% of patients with IFP affecting the small intestine develop intussusception and are diagnosed by pathological examination of the resected specimen, as in the case presented here.
