A Case of Ectopic Sebaceous Glands in the Esophagus / 대한소화기내시경학회지

ABSTRACT

Ectopic sebaceous glands have been reported in the organs of an ectodermal origin such as the oral cavity, genitals, eye and orbit, nipples, palm and soles, and the parotid glands. Their presence in the esophagus, which is an organ of endodermal origin, is a very rare and interesting anomaly. Whether ectopic sebaceous glands in the esophagus are the result of congenital misplacement or acquired metaplastic change remains unclear. We report here on a patient with sebaceous glands in the esophagus, and this was diagnosed by endoscopic biopsy.
