Tonsillar cysts in the throat of a 68-year-old man. Tonsils are oval-shaped masses of spongy lymphoid tissue on either side of the back of the mouth. They play a role in the body's response to infection, producing antibodies for the immune system and trapping and destroying micro-organisms that enter the throat. A cyst is a fluid-filled sac. | |
