Pyogenic granuloma (PG) is a polypoid lobular capillary hemangioma rarely observed in the gastrointestinal tract. Only a few cases in the small bowel have been described in the literature. A 58-year-old man had been suffering from general fatigue and severe anemia. Esophagogastroduodenoscopy and colonoscopy did not reveal any significant bleeding. Abdominal computer tomography revealed a hypervascular tumor in the small intestine. Oral double-balloon endoscopy (DBE) detected a polypoid lesion (2 cm in diameter) in the jejunum. We performed laparoscopic-assisted partial resection of the jejunum. The histological features of the tumor were consistent with PG. The patient's anemia gradually improved without the need for oral iron after surgery. In this case report, we present a case of pyogenic granuloma in in the jejunum that was detected by DBE.
