Heterotopic sebaceous glands in the esophagus: case report with review of the literature]

Heterotopia of sebaceous glands is a very rare endoscopically indistinct benign finding in the esophagus. To date only 30 cases have been reported in the literature. The lesions exhibit a considerable variation in number and size. No malignant transformation has yet been reported. From the pathologists' point of view an inflammatory or neoplastic process has to be excluded as the cause of the non-distinctive endoscopic findings.
