With tongue depressor or indirect laryngoscopy, there is hypertrophic lymphoid tissue in the root of the tongue, which is granular and covers the root of the tongue, symmetrically on both sides or on one side. In severe cases, the lymphoid tissue may cover the epiglottis valley and may also extend to the pharyngeal side and connect with the tonsils. Because of the infection of lymph nodes in the lingual tonsils, the diagnosis of lingual tonsillar hypertrophy can be seen in the yellowish-white dotted abscess under the mucosa. On examination of the oropharynx, a mucopurulent plug is often extruded from the nasopharynx as a result of gagging. The child’s expression is painful, with nasopharyngeal reflexoscopy or nasopharyngoscopy can be seen in the nasopharynx at the top and the posterior wall there are several deep grooves longitudinally divided lobulated lymphoid tissue mass, longitudinal grooves are sometimes seen in the pus and shedding of tissue debris. If the proliferation of pharyngeal tonsils is very large, the nasopharynx can be completely filled and cover the posterior nostril. Examination of the child can be difficult by palpation (soft lymphoid masses on the roof and posterior wall of the nasopharynx can be palpated with the finger). Enlarged lymph nodes can be detected in the neck and at the posterior border of the sternocleidomastoid muscle, or in the mastoid and mandibular branches. Care should be taken to differentiate it from retrosplenial pharyngeal tumors, such as lymphosarcoma.
