回腸inflammatory fibroid polypの1例

Inflammatory fibroid polyp (IFP) is submucosal tumor-like benign tumor and often detected after abdominal pain due to intussusception. It is rare that IFP is diagnosed before surgery. We experienced a 70-year-old female patient who showed right lower abdominal pain and elevated serum C-reactive protein. CT scan revealed thickened and edematous wall of ileum and colonoscopy revealed pedunculated lesion with defected mucosa in the terminal ileum. Histopathological exam showed granulation tissue of the ileum that provided a diagnosis as IFP of the ileum. Laparoscopic assisted ilectomy was performed and no relapse has been seen. The lesion located at the ileocecal area and chronic physical stimulation resulted in mucosal defection that gave us a rare chance to preoperative histopathological diagnosis of IFP of the small intestine.
