舌扁桃体（LT）位于舌底，位于环瓣乳头后方，由舌会厌正中韧带分隔的淋巴组织聚集体组成，该韧带将舌扁桃体分成左右两半。韧带两侧的扁桃体组织呈离散的向上突出的圆形结节。每个凸起被非角化上皮覆盖，并有一个由上覆上皮内陷形成的中央隐窝。邻近粘液腺的导管进入隐窝，作为冲洗机制清洁隐窝。一层薄薄的纤维结缔组织囊将LT与舌下肌肉组织隔离开来。舌扁桃体组织随着年龄的增长而退化。LT的肥大和病理改变可发展并引起主观症状。患者主诉包括喉咙痛、吞咽困难、球感、呼吸困难、阻塞性睡眠呼吸暂停、发音困难、口臭和耳痛。扁桃体结石在腭扁桃体经常被报道，但LT也可以发展扁桃体结石。在英语牙科文献中仅发现1例LT扁桃体结石。由于其文献罕见，本报告提出了一个偶然发现舌扁桃体的病例。当这类病例引起专业人士的注意时，诊断技能就会提高。(C) 2019年美国口腔颌面外科医师协会
The lingual tonsil (LT), located at the base of the tongue posterior to the circumvallate papillae, consists of aggregates of lymphoid tissue separated by a median glossoepiglottic ligament that splits the LT into right and left halves. Tonsillar tissue on either side of the ligament exhibits discrete round nodules that project upward. Each prominence is covered by nonkeratinized epithelium and has a central crypt formed by an invagination of the overlying epithelium. Ducts of adjacent mucous glands empty into the crypt, serving as a flushing mechanism to cleanse the crypt. A thin fibrous connective tissue capsule isolates the LT from the underlying tongue musculature. Lingual tonsillar tissue tends to regress with aging. Hypertrophy and pathologic changes of the LT can develop and cause subjective symptomatology. Patient complaints include sore throats, dysphagia, globus sensation, dyspnea, obstructive sleep apnea, dysgeusia, halitosis, and otalgia. Tonsilloliths in the palatine tonsil are often reported, but the LT also can develop a tonsillolith. Only 1 report of LT tonsilloliths was found in the English-language dental literature. Because of its literary rarity, this report presents a case of an incidental finding of a lingual tonsillolith. Diagnostic skills are sharpened when such cases are brought to the attention of the profession. (C) 2019 American Association of Oral and Maxillofacial Surgeons
