Pyogenic granuloma is a lobular capillary hemangioma that occurs mostly on the skin, and occasionally on the mucosal surface of the oral cavity, but very rarely in the gastrointestinal tract. We report the case of a 63-year-old woman who suffered from palpitations, and iron deficiency anemia for 5 years. Esophagogastroduodenoscopy and colonoscopy could not reveal significant bleeding focus. She had not received medical treatment except for oral iron. Capsule endoscopy revealed a bleeding focus in the small intestine. Afterwards, we carried out double balloon endoscopy to treat the lesion. We found a subpedunculated polyp in the small intestine at 100 cm away from ileocecal valve by double balloon endoscopy and resected it endoscopically. The histological features of the polyp were consistent with pyogenic granuloma. Anemia had improved gradually without giving oral iron after polypectomy.
化脓性肉芽肿是一种发生于皮肤，偶见于口腔黏膜表面，但非常罕见于胃肠道的小叶状毛细血管血管瘤。我们报告了一例 63 岁女性，因心悸和缺铁性贫血 5 年就诊。食管胃十二指肠镜和结肠镜均未能发现明显的出血病灶。除了口服铁剂外，她没有接受任何治疗。胶囊内镜显示小肠有出血病灶。随后，我们进行双气囊内镜检查以治疗病变。通过双气囊内镜，我们在距回盲瓣 100cm 的小肠处发现一个带蒂息肉，并在内镜下切除。息肉的组织学特征符合化脓性肉芽肿。息肉切除后，患者未再口服铁剂，贫血逐渐改善。
