Leukoplakia. Endoscope view of the larynx (voice box) of a patient showing leukoplakia (keratosis, white, centre) of the vocal cords due to laryngitis. Leukoplakia is a thickening of the body tissues that develops in response to chronic (long-term) irritation. It usually clears up if the source of irritation is removed, but in extreme cases surgical removal of the affected area is required. Laryngitis is the inflammation of the larynx caused by infection with bacteria or viruses, or by irritation due to ingested chemicals. Treatment involves resting the voice and remaining in a warm, moist environment.
