Basics
Lateral trangangina is the name given to a specific inflammation of the pharynx, which mainly affects the lymph vessels running down from the upper posterior pharyngeal wall (= lateral cords). In contrast to other inflammations of the pharynx, such as pharyngitis, lateral gangrene occurs relatively rarely.
The lymph vessels of the lateral cords originate near the Tuba auditiva (Eustachian tube), which forms a connection between the middle ear and the nasopharynx. For this reason, lateral gangrene can also spread to the ear and cause ear pain. Inflammatory changes in the lateral cords are usually marked by redness and swelling and are often covered with small, white stipples.
