Esophageal vascular malformations are very rare. Herein, we describe a rare polyp formed by an abnormally large vessel that bled profusely after biopsy. Despite endoscopic procedures, the patient continued to bleed and underwent emergency surgery. Histopathological examination revealed an abnormally large blood vessel with a thick wall in the upper part of the lamina propria mucosae and covered by squamous cell epithelium. The elevated lesion, which was endoscopically diagnosed a small polyp, was in fact an abnormally large artery covered by squamous cell epithelium. Massive bleeding after biopsy of an esophageal polyp is apparently so rare that it has not, as yet, been described.
