As of now, the histogenesis of ectopic sebaceous glands in the esophagus is unknown; whilst it could be a congenital abnormality, a majority of authors defined it like an acquired metaplastic process. From a practical standpoint, it is an incidental finding that on occasion, as in our case, has been associated with gastroesophageal reflux disease, not requiring treatment or endoscopic follow-up and, and needing a differential diagnosis from Candida infection and glycogen acanthosis.
