Abstract
Twenty year old man was admitted for melena. Endoscopy was performed, and protruding lesion was observed at the descending part of the duodenum (Figure 1). Capillary hemangioma was confirmed by forceps biopsy (Figure 2). Hemangioma or hemorrhagic lesion was not found at the other sites. The lesion was suspected as the cause of melena, suggesting the possibility of recurrence of bleeding. So ethanol injection therapy was performed. These hemangioma disappeared 3 months later. The patient became well except transient abdominal pain upon the injection therapy. It seems that this is a safe and effective hemostatic therapy. Duodenal hemangioma is not common, and only 5 cases have been reported in Japan, and all of which are cavernous hemangioma. This is the first report of capillary hemangioma of the duodenum in Japan.
