UNDER the heading cystoma of the larynx, St. Clair Thompson1 states that such cysts are due to retention from obstruction in the duct of a muciparous gland or distention of a lymphatic vessel. Their commonest situation is on the anterior surface of the epiglottis. They are also found on the ventricular bands, the aryepiglottic folds, and the external (pharyngeal) surface of the larynx. They rarely occur on the vocal cords, and when a growth in this situation collapses with escape of fluid upon being grasped or incised, it is generally a fibroma which has undergone edematous degeneration. These cysts may be broad-based or pedunculated. The surface is smooth, globular, and semitranslucent, and blood vessels are frequently seen coursing over it. The color is grayish-yellow, pink, or red. Simple incision is generally not effective. Part of the cyst wall should be torn away with forceps or a hole burnt into
