The discovery of sebaceous glands in ectoderm-derived tissues such as the oral cavity, parotid glands, and external genitalia is a frequent finding. On the contrary, the presence of sebaceous glands in the esophagus, which is an organ of endodermal origin, is rare: there are fewer than thirty cases reported, most of them affecting the esophagus in a patchy pattern.

 

Case report

A 50-year-old woman suffering from heartburn and acid regurgitation was referred to our department for endoscopic examination. Endoscopy demonstrated more than one hundred tiny, rounded, elevated, white-yellowish lesions distributed throughout the entire esophagus (Fig. 1), which were identified during the histopathological examination as sebaceous glands (Fig. 2).

 

Discussion

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.
