Abstract:
Sebaceous glands are cutaneous annexes located in the dermis. Focal spots of ectopy of these glands are frequently identified in ectodermal tissues: they represent Fordyce's disease. However, only a few cases of ectopic sebaceous glands have been mentioned in non-ectodermic tissue. Fordyce spots of esophageal location are unusual, and most of them have been diagnosed from biopsy specimens. We report two cases of ectopic sebaceous glands in esophagus, the first diagnosed from a resected specimen, the second from biopsies. A literature review is carried out.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
