The lingual papillae are numerous tiny papillary projections located on the back and sides of the tongue, consisting of epithelium and subepithelial connective tissue. Chronic lingual tonsilitis (chronic lingual tonsilitis) or hypertrophy of the lingual tonsils, mostly from recurrent episodes of acute lingual tonsillitis to chronic. Most of them are related to chronic inflammation of the upper respiratory tract, excessive smoking and drinking, stimulation of irritating foods and harmful gases. It often coexists with chronic tonsillitis, and compensatory hypertrophy of the lingual tonsils may also occur after tonsillectomy. The disease occurs mostly in adults and is rare in children. If the tongue is pressed with a tongue depressor or indirect laryngoscopy, hypertrophic lymphoid tissue can be seen at the root of the tongue in a granular pattern, symmetrical on both sides or on one side. In severe cases, the lymphatic tissue is covered with the valley of the epiglottis and can also extend to the side of the pharynx to connect with the tonsils. Due to the lymphoid follicular infection in the lingual tonsils, small yellowish-white submucosal abscesses can be seen. It is distinguished from chronic tonsillitis. It is caused by the accumulation of bacteria and secretions in the tonsillar fossa. These accumulated bacteria continuously secrete toxins and spread throughout the body through the network of blood vessels surrounding the glandular fossa. As a result, the tonsils become the focus of many systemic diseases such as rheumatic fever and nephritis, and this is where the danger lies.
