Cystadenoma may be defined as adenoma that has undergone cystic degeneration. It is common in the breast and the ovary but extremely rare in the larynx. In fact, adenoma, from which it develops, is very unusual in this situation. A number of laryngologists of considerable experience never have observed a tumor with the microscopic diagnosis of simple adenoma of the larynx and some doubt its occurrence. However, numerous mucous glands are present in the larynx, and at times these may give rise to a glandular cell tumor. Recognition of the stage in the transition of an adenomatous tumor at which it has sufficiently pronounced cystic features to permit of its designation as cystadenoma will naturally depend on the personal equation of the pathologist. The present report is based on 4 cases in which advanced cyst formation was present.
Few reports of cases of cystadenoma of the larynx appear
