[Pulmonary and laryngeal tuberculosis. Study of 26 patients].
A description is reported of tuberculosis cases (TBC) with symptomatic laryngeal involvement diagnosed and treated from 1982 to 1994. Twenty-six out of 2,800 (0.9%) patients diagnosed with TBC had laryngeal symptoms. Twelve patients underwent laryngeal biopsy and the disease was diagnosed in 11; the remaining 15 patients were diagnosed on the basis of the typical lesions at laryngoscopy and resolution with specific therapy; in all of them there was a pulmonary TBC associated. The mean time of clinical laryngeal symptoms was five months and the most common symptom was dysphonia. There were factors which increased the risk for TBC in 16 patients (61.5%), alcoholism being the most common symptom in 10 (38%) patients. X-Ray examination revealed bilateral infiltrates or cavitation in 81% of patients. Sputum examination for acid-fast bacilli was positive in 15 (58%) and culture for Mycobacterium tuberculosis was positive in all of them. All patients adhered correctly to the therapeutic regimen and the clinical course was towards healing: no patient had laryngeal carcinoma after one year of follow-up. The incidence of symptomatic laryngeal TBC in our environment is low and usually presents in patients with risk factors, particularly alcoholism, with a long evolution of the disease and associated with extensive pulmonary TBC. The coexistence with laryngeal carcinoma is exceptional; therefore, when the association of laryngeal symptoms and active pulmonary TBC is present it is reasonable to reserve the laryngeal biopsy for those patients with lymph node enlargement, risk factors, or when symptoms persist after a correct therapeutic regime has been instituted.
