title: Sebaceous glands in the esophagus. First case observed grossly.
abstract: Minute, pale tan macules of the esophageal mucosa observed at autopsy proved, on microscopical study, to be sebaceous glands unaccompanied by hair follicles. Metaplasia of pluripotent cells is postulated as their origin in this purely endodermal tissue, rather than derivation from islands of misplaced epidermis.
