Abstract
A 25-year old man was admitted to our hospital with right lower abdominal pain. Abdominal ultrasonography painted out the ileal tumor, and colonoscopy revealed the sub-mucosal tumor about 20rnm in diarneter of the terminal ileum.17 days later rc-colonoscopyrevealed that the tumor was growing semipedunculated, and the top of the tumor was erosiveand the mucasa around the tumor was reddish, and the part of the tumor was resected byendoscopic polypectomy. Histopathological examination showed that the tumor consisted ofblood vessels, loose fibrous stroma and in.filtration of inflammatory cells mainly composod ofeosinophiles, and so the diagnosis was inflammatory fibroid polyp. The tumor was growing, andthe invagination occurred. So meal resection about 4cm in length with the tumor was perfor-med. Inflammatory fihroid polyp of the small intestine is rare and extremely difficult in thepreoperative diagnosis. We reported a case of the inflamrnatory fibroid polyp of the smallintestine with preoperative histopathological diagnosis.
