Abstract
Cavernous hemangiomas of the gastrointestinal tract are extremely rare. In particular, the diagnosis of small bowel hemangiomas is very difficult in children. A 13-year-old boy presented at the outpatient clinic with dizziness and fatigue. The patient was previously diagnosed with iron-deficiency anemia at 3 years of age and had been treated with iron supplements continuously and pure red cell transfusion intermittently. Laboratory tests indicated that the patient currently had iron-deficiency anemia. There was no evidence of gross bleeding, such as hematemesis or bloody stool. Laboratory findings indicated no bleeding tendency. Gastroduodenoscopy and colonoscopy results were negative. To obtain a definitive diagnosis, the patient underwent capsule endoscopy. A purplish stalked mass was found in the jejunum, and the mass was excised successfully. We report of a 13-year-old boy who presented with severe and recurrent iron-deficiency anemia caused by a cavernous hemangioma in the small bowel without symptoms of gastrointestinal bleeding.
