A prospective study searching for associated mycobacterial infection of the upper aerodigestive tract in patients with cervical tuberculous lymphadenitis (TBLN) was carried out. One hundred and thirteen patients with a clinical suspicion of cervical TBLN were included. All patients had a physical examination of the upper aerodigestive tract. Routine endoscopy and biopsy of the nasopharynx were performed. All of them had surgery to the cervical lymph node. Seventy-five patients had histologically confirmed cervical TBLN. Culture of the lymph node specimen showed Mycobacterium tuberculosis in 68 (90 per cent). In 45 (60 per cent) patients with cervical TBLN the primary foci of infection could not be found. Twenty-nine (39 per cent) had radiographic evidence of active or healed pulmonary tuberculosis. Sputum culture from two patients showed Mycobacterium tuberculosis. Five patients (six per cent) had tuberculous nasopharyngitis. In one of them (one per cent) the tuberculous nasopharyngitis was primary as no other evidence of mycobacterial infection was found. In the present study, mycobacterial infection of other parts of the upper aerodigestive tract was not found.
开展了一项前瞻性研究，以探寻颈淋巴结结核（TBLN）患者上呼吸道和消化道的相关分枝杆菌感染情况。纳入了113例临床怀疑为颈淋巴结结核的患者。所有患者均对上呼吸道和消化道进行了体格检查。对鼻咽部进行了常规内镜检查及活检。所有患者均接受了颈部淋巴结手术。75例患者经组织学确诊为颈淋巴结结核。淋巴结标本培养显示68例（90%）为结核分枝杆菌。45例（60%）颈淋巴结结核患者未发现感染的原发灶。29例（39%）有活动性或已愈合肺结核的影像学证据。2例患者的痰培养显示为结核分枝杆菌。5例患者（6%）患有结核性鼻咽炎。其中1例（1%）结核性鼻咽炎为原发性，未发现其他分枝杆菌感染证据。在本研究中，未发现上呼吸道和消化道其他部位的分枝杆菌感染。
