Abstract
A 46-year-old woman was detected an absence of haustra on the right side of the colon and a large filling defect in the cecum by barium enema study at local hospital and referred to our hospital for further evaluation. Colonoscopy revealed diffuse mucosal redness and several aphthous ulcers between the splenic flexure and the cecum, and these findings were suspected of ulcerative colitis. Biopsy of the right colon confirmed a diagnosis of ulcera-tive colitis. The colonoscopy also showed a pedunculated polyp, about 4cm in diameter, in the cecum and endoscopic snare polypectomy was performed. Microscopically, the polyp consisted of fibroblastic and vascular proliferation with inflammatory cell infiltration, predominantly eosinophils. A histopathological diagnosis of inflammatory fibroid polyp was made. Inflammatory fibroid polyp of the colon is rare and to our knowledge it has not been found previously in combination with ulcerative colitis.
