Lymphatic follicular hyperplasia in the pharynx does not become cancer. Lymphatic follicles are an important part of the pharyngeal lymphatic ring. When encountering chronic inflammatory infections, prolonged intake of spicy and stimulating foods as well as gastrointestinal dysfunction and acid reflux with acidic water and acid gas stimulation, they can cause lymphatic follicular hyperplasia in the pharynx. On examination, a large number of small reddish bulges with soft texture and no pain can be seen at the root of the tongue in the posterior pharyngeal wall and at the valley of the epiglottis, which can cause dryness, sore throat and foreign body sensation in the throat of the patient, but normal when swallowing. In terms of treatment, if the patient does not have any symptoms, the lymphatic follicles can be left untreated. If the patient has severe foreign body sensation, laser and microwave can be performed to knock out the lymphatic follicles and oral treatment with Slowlime. It is also necessary to avoid the intake of spicy and stimulating food, drink more water, pay more attention to rest and adjust the gastrointestinal function in order to cure.
