RESUMEN
Introducción: la tuberculosis (TB) es una enfermedad infectocontagiosa granulomatosa crónica, producida por Mycobacterium tuberculosis. En Uruguay se ha notificado un aumento en el número de casos, con una incidencia reportada en 2017 de 28,6/100.000 habitantes, siendo de 6,67/100.000 en menores de 15 años. La tuberculosis laríngea es una forma poco frecuente y evolucionada de tuberculosis, que suele manifestarse con disfonía crónica. Su diagnóstico requiere un alto índice de sospecha. Objetivo: describir un caso clínico de presentación poco frecuente en la edad pediátrica. Caso clínico: adolescente de 13 años, sana, vacunas vigentes, con antecedentes de conductas sexuales activas y papilomatosis laríngea diagnosticada por laringoscopía directa como causa de disfonía crónica. Consulta en emergencia por dolor abdominal, constatándose al examen clínico adelgazamiento asociado a síntomas respiratorios y síndrome tóxico bacilar asociado a disfonía crónica de cuatro meses de evolución, por lo cual se plantea tuberculosis laríngea e ingresa para estudio. Niega contacto de tuberculosis. En la radiografía de tórax se constata lesión cavernosa en vértice pulmonar izquierdo. Las baciloscopías de esputo fueron positivas (directo y cultivo) confirmando el planteo de TB pulmonar y laríngea. Se realizó tratamiento antituberculoso supervisado con excelente evolución posterior. Conclusiones: la tuberculosis es una enfermedad reemergente en nuestro país, que requiere un alto índice de sospecha. Su diagnóstico sigue siendo un desafío para los pediatras ya que la confirmación diagnóstica no siempre es posible. En este caso clínico la sospecha clínica frente a una disfonía crónica asociada a síntomas respiratorios fue fundamental para establecer el diagnóstico, a pesar de no contar con nexo epidemiológico.
Introduction: tuberculosis (TB) is an infectious, chronic granulomatous disease caused by Mycobacterium tuberculosis. An increase in the number of cases has been reported in Uruguay, with an incidence reported in 2017 of 28.6/100,000 inhabitants, being 6.67/100,000 in children under 15 years of age. Laryngeal tuberculosis is a rare and evolved form of tuberculosis, which usually shows chronic dysphonia, which requires high levels of suspicion. Objective: to describe a clinical case with a rare presentation in pediatric age. Clinical case: 13-year-old female adolescent, healthy, fully vaccinated, with a history of active sexual behaviors and laryngeal papillomatosis diagnosed by direct laryngoscopy as a cause of chronic dysphonia. The emergency consultation was caused by abdominal pain, confirming the clinical examination weight loss associated with respiratory symptoms and bacillary toxic syndrome associated with chronic dysphonia of four months of evolution, for which laryngeal tuberculosis was considered and she was admitted for screening. She denies having been in contact with tuberculosis. The chest X-ray revealed a cavernous lesion in the left pulmonary apex and sputum smears were positive (direct and culture), confirming the suggestion of pulmonary and laryngeal TB. Supervised anti-tuberculosis treatment was performed with excellent subsequent evolution. Conclusions: tuberculosis is a re-emerging disease in our country, which requires a high level of suspicion. Its diagnosis remains a challenge for pediatricians since diagnostic confirmation is not always possible. In this clinical case, clinical suspicion of chronic dysphonia associated with respiratory symptoms were key factors to establish the diagnosis, despite not having a clear epidemiological link.
Introdução: a tuberculose (TB) é uma doença infecciosa granulomatosa crônica causada pelo Mycobacterium tuberculosis. No Uruguai, houve aumento do número de casos notificados, com uma incidência notificada em 2017 de 28,6/100.000 habitantes, sendo 6,67/100.000 casos de menores de 15 anos. A tuberculose laríngea é uma forma rara e evoluída de tuberculose, que geralmente se manifesta com disfonia crônica, exigindo alto índice de suspeita. Objetivo: descrever um caso clínico de apresentação pouco frequente em idade pediátrica. Caso clínico: menina adolescente de 13 anos, saudável, totalmente vacinada, com história de comportamentos sexuais ativos e papilomatose laríngea diagnosticada por laringoscopia direta como causa de disfonia crônica. Consulta de urgência por dor abdominal, comprovando emagrecimento associado a sintomas respiratórios e síndrome bacilar tóxica associada a disfonia crônica de quatro meses de evolução, para a qual foi considerada tuberculose laríngea e a paciente foi internada para estudo. Ele nega contato com tuberculose. A radiografia de tórax revelou lesão cavernosa em ápice pulmonar esquerdo e as baciloscopias de escarro foram positivas (direta e cultura) confirmando a sugestão de TB pulmonar e laríngea. O tratamento antituberculose supervisionado foi realizado com excelente evolução subsequente. Conclusões: a tuberculose é uma doença reemergente em Uruguai e requer alto índice de suspeita. Seu diagnóstico permanece um desafio para o pediatra, pois a confirmação diagnóstica nem sempre é possível. Neste caso clínico, a suspeita clínica de disfonia crônica associada a sintomas respiratórios foi fundamental para o estabelecimento do diagnóstico, apesar de não ter vínculo epidemiológico.

INTRODUCTION: Laryngeal tuberculosis (LTB) is the most frequent granulomatous disease of the larynx and represents less than 2% of extrapulmonary TB cases. There are no pathognomonic clinical and endoscopic features of this disease and studies on LTB that can assist in its diagnostic characterization are lacking. OBJECTIVE: To identify factors associated with clinical and topographical features of LTB. METHOD: a retrospective cross-sectional study was conducted from the medical records of 36 patients with confirmed LTB diagnosis. RESULTS: Dysphonia and cough were the main symptoms presented by patients and the true vocal folds the most frequently affected site. The average of the duration of the disease evolution was significantly higher in patients with dysphonia than in patients without this symptom. We observed association between dysphonia and true vocal fold lesions and between odynophagia and lesions in the epiglottis, arytenoids and aryepiglottic folds. Odynophagia was more frequent in individuals with lesions in four or more laryngeal sites. Weight loss equal or above 10% of the body weight was more frequent in patients with odynophagia as first symptom and in patients with ulcerated lesion. Dyspnea on exertion was more frequent in individuals with more extensive laryngeal lesions. The percentage of smokers with lesions in four or more laryngeal sites was greater than that found in non-smokers. Laryngeal tissue fragment bacilloscopy and culture examinations were less positive than sputum ones. CONCLUSIONS: Smoking appears to be associated with the development of more extensive LTB lesions, and LTB with dyspnea on exertion and odynophagia with consequent impairment of nutritional status. We emphasize the need for histopathologic confirmation, once positive sputum bacteriological examinations seem not to necessarily reflect laryngeal involvement.

Since the introduction of antituberculous medications, the incidence of laryngeal tuberculosis (LTB) has decreased. However, it is a fact the increasing number of cases of pulmonary or extrapulmonary TB mainly caused by the Acquired Immunodeficiency Syndrome. We report the clinical case of a 72 years old male with dysphonia secondary to LTB which masqueraded a carcinoma. It's certain diagnosis was the histopathologic exam of the biopsy obtained by microsurgery. There was a residual TB in lung after a complete study of Internal Medicine Department.

A 30-year-old woman presented with a painless left upper neck swelling for more than a week. Fibrolaryngoscope examination suggested nasopharyngeal carcinoma. FDG PET/CT was performed for an initial staging, which revealed intense activity in the soft tissue mass in the nasopharynx and cervical lymph nodes. However, biopsy from the nasopharyngeal lesion demonstrated tuberculosis.

A three and a half-year-old boy developed stridor after insertion of grommets for bilateral secretory otitis media. Despite treatment with steroids systemically and locally, antibiotics and an antihistamine, the stridor worsened. Microlaryngotracheobronchoscopy (MLB) demonstrated laryngeal granulations, in which, by auramine and Ziehl-Neelsen staining, acid-fast bacilli were seen, and from which subsequently Mycobacterium tuberculosis grew in culture. Following the MLB the child became comatosed and a clinical diagnosis of tuberculosis involving the central nervous system was made. Despite quadruple antituberculous chemotherapy he died 8 days later. A Mantoux test was negative and a chest radiograph was normal. Acid-fast bacilli were not demonstrated on repeated examinations of cerebrospinal fluid, nor were they grown ante mortem or post mortem from samples of cerebrospinal fluid.

A patient with laryngeal and pulmonary tuberculosis is described. The similarity between the clinical presentation and gross appearance of laryngeal carcinoma and tuberculosis in this patient and others reported in the literature is emphasized. Laryngeal biopsy is necessary to establish the correct diagnosis, but this must be done only after the proper precautions are taken to reduce the risk of infection to the physician performing the biopsy. Examination of the chest x-ray and acid-fast stain of the sputum are rapid and highly reliable screening tests for laryngeal tuberculosis.

Laryngeal tuberculosis is usually a complication of pulmonary tuberculosis. Recent studies have described a change in the clinical features of laryngeal tuberculosis. We present 15 cases of laryngeal tuberculosis treated at the Osaka Prefectural Habikino Hospital between 1993 and 2000. The results showed a mean age of 51 years, a male predominance by 2.75 to 1, and a 20% incidence (n = 3) of negative chest radiographic findings. The prominent presenting symptom was hoarseness (73.3%), and systemic symptoms were relatively rare. Seven patients showed ulcerative lesions, 5 showed granulomatous lesions, and the remaining 3 showed nonspecific inflammatory lesions in the larynx. Laryngeal lesions did not show any predilection for specific laryngeal sites in our series. In contrast to earlier studies, our study shows variations in clinical features of laryngeal tuberculosis. Physicians should consider tuberculosis in the differential diagnosis of laryngeal disease.

The incidence of laryngeal tuberculosis is increasing worldwide. To ensure early diagnosis it is important for physicians and otolaryngologists to recognize its cardinal signs and symptoms. We present two recent cases of laryngeal tuberculosis that presented to our department. We outline potential pitfalls in diagnosis, and highlight the importance of obtaining a tissue diagnosis. The literature is reviewed, and the treatment options outlined.

Laryngeal tuberculosis is now an uncommon disease in the United Kingdom. A series of ten cases is reported. In contrast to the pre-chemotherapy era, when the disease was associated with advanced cavitated pulmonary tuberculosis and was highly infectious, it now presents in a manner similar to laryngeal carcinoma except that painful dysphagia is a prominent symptom. All such patients should have a chest X-ray carried out as part of their initial investigation. Sputum is almost always positive for tubercle bacilli on direct films. Direct laryngoscopy and biopsy are necessary if a carcinoma is suspected. The change of pattern of the disease may be due to the fact that the larynx now usually becomes involved by haematogenous spread rather than by direct spread along the airways. Laryngeal tuberculosis is now no more infectious than pulmonary tuberculosis, and responds well to antituberculous chemotherapy. Symptoms resolve completely within three weeks if corticosteroids are given in combination.

A middle-aged native Danish man became aphonic with chronic laryngitis. The symptoms persisted despite antibiotic treatment, and chest X-ray disclosed a central pulmonary infiltrate. Histopathology on specimens from the larynx and lung and microscopy and culture of the sputum revealed primary lung tuberculosis with spread to the larynx. At presentation, laryngeal tuberculosis often mimics non-specific chronic laryngitis or laryngeal carcinoma. It should be suspected when the clinical course is unusual. Tuberculosis may develop in the absence of risk factors.

Tuberculosis of the larynx has become a rarity since the discovery of streptomycin in 1944. In this article a personal case history is described, together with a review of the literature and an analysis of the main clinical features of tuberculosis of the larynx. The pseudo-tumoural form of tuberculosis is often indicative of the presence of pulmonary tuberculosis, but may also occur in isolation. Histology is often the only definitive diagnostic test.
