Endoscopic submucosal dissection of a proximal esophageal hemangioma accompanied with gastrointestinal bleeding.

A 57-year-old female with a history of chronic gastritis presented with a 3-day history of melena and asthenia. Physical examination and laboratory data were normal besides a mild tachycardia and microcytic hypochromic anemia. Gastroscopy showed a 20-mm diameter, bluish submucosal mass at the esophageal entrance, swinging to the hypopharynx once vomit occurred (Fig. 1a). There was no evidence of hemorrhage in the stomach and intestines. She was admitted for intravenous fluid therapy. Contrast-enhanced computed tomography revealed a poorly defined enhancing mass almost obstructing the esophageal orifice, but well separated from adjacent tissue (Fig. 1b). Therefore, submucosal hemangioma of the proximal esophagus was diagnosed.
