Submucosal adenoma of the esophagus: case report and review of the literature

A 60-year-old woman complaining of abdominal discomfort was found at endoscopy to have a dome-shaped esophageal polyp, located 22 cm from the incisor teeth and covered by normal epithelium. Histologic examination after endoscopic removal showed a submucosal esophageal gland adenoma. This is the ninth reported case of this entity. Eleven years later, the patient remains well with no evidence of esophageal disease. We review all nine reported cases of submucosal adenoma of the esophagus.
