Sialadenoma papilliferum of the esophagus is an extremely rare benign tumor that derives from the submucosal gland duct of the minor salivary gland. A 45-year-old man underwent upper gastrointestinal series. A 13 mm diameter esophageal polyp was suspected in the mid esophagus. Endoscopy examination revealed a pedunculated polyp arising from the posterior wall of the esophagus. The head of the polyp was covered with exudate and was slightly nodular but the pedicle had normal mucosa. We performed endoscopic mucosal resection (EMR) and the histological examination of the polyp showed that it was compatible with sialadenoma papilliferum of the esophagus.
