Tuberculosis pulmonar y laríngea: una forma poco frecuente de presentación en la edad pediátrica / Pulmonary and laryngeal tuberculosis: a rare presentation in pediatrics / Tuberculose pulmonar e laríngica: uma apresentação pouco frequente na idade pediátrica

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.

Tuberculosis laríngea secundaria a foco pulmonar primario inadvertido: caso clínico / Laryngeal tuberculosis secondary to an inadvertent primary pulmonary focus: clinical case

Introducción: La tuberculosis laríngea es una entidad sumamente rara en países del primer mundo, sin embargo, en nuestro medio no es extraño, como país latinoamericano, sospechar esta patología como una de las causas de disfonía y lesiones granulomatosas en la actualidad. La tuberculosis laríngea debe considerarse dentro de las patologías en pacientes con disfonía de larga evolución que no responden al tratamiento común, esta entidad puede ser confundida con neoplasias. Reporte de caso: Se presenta el caso de una mujer en la cuarta década de la vida con disfonía crónica de 6 meses de evolución, que fue remitida para laringoscopia. Se localizaron neoformaciones granulomatosas acompañadas de edema en ambas cuerdas vocales, sometidas a biopsia, con resultados con la tinción de hematoxilina-eosina de células gigantes multinucleadas de Langhans y la tinción Zielh-Nielsen fue positiva para bacilo alcohol ácido resistente. La radiografía de tórax mostró lesiones reticulonodulares sugestivas de tuberculosis pulmonar. Conclusión: Un alto nivel de sospecha y un diagnóstico temprano pueden limitar las complicaciones y facilitar un manejo oportuno de estos casos. Es necesario sospechar de tuberculosis laríngea en pacientes que presentan disfonía crónica, especialmente cuando se asocia con síntomas constitucionales, aunque no siempre los presentan, por otro lado, en algunos casos, no existe asociación con inmunodeficiencia.

Introduction: Laryngeal tuberculosis is an extremely rare entity in first world countries, however, it is not strange in our environment as a Latin American country to suspect this pathology as one of the causes of dysphonia and granulomatous lesions today. Laryngeal tuberculosis should be considered within the pathologies in patients with long-standing dysphonia that do not respond to common treatment, this entity can be confused with neoplasms. Case report: We present the case of a female in the fourth decade of life with chronic dysphonia of six months of evolution, who was referred for laryngoscopy, granulomatous neoformations accompanied by edema in both vocal cords were located, subjected to biopsy with results with hematoxylin staining. Langhans multinucleated giant cell eosin and Zielh-Nielsen staining were positive for acid-fast bacillus. Chest X-ray showed reticule-nodular lesions suggestive of pulmonary tuberculosis. Conclusion: A high level of suspicion and an early diagnosis can limit complications and facilitate timely management of these cases. It is necessary to suspect laryngeal tuberculosis in patients with chronic dysphonia, especially when associated with constitutional symptoms, although they do not always present them; on the other hand, in some cases, there is no association with immunodeficiency

Primary laryngeal tuberculosis: a rare cause of chronic laryngitis.

Tuberculosis (TB) is not only a major public health problem of developing countries like India, since its incidence is increasing due to increasing immune-depressive states including HIV, malignancies and cytotoxic chemotherapy. Laryngeal TB occurs usually a secondary to associate with pulmonary disease, and primary form is very rare in immune-competent people. We report a 49‑years‑old non-smoker, non-diabetic, immunocompetent man presenting with chronic dry cough and hoarseness without any constitutional symptoms, family or contact history of TB. The chest X-ray was normal. Laryngoscopy showed congested larynx without any ulcer or mass and normal vocal cords. Biopsy from aryepiglottic fold was suggestive of TB, but caseation was absent. Diagnosed to be primary laryngeal TB, he responded well to anti-tubercular therapy. Primary laryngeal TB without pulmonary TB can mimick chronic laryngitis. Before anti-tubercular drug use, in the 1950’s, it was a common and frequently fatal disease but it’s clinical features, age group involved and prognosis has changed over the last few decades. It is more infectious than pulmonary form primarily due to delayed diagnosis. It can mimick a common condition like chronic laryngitis, although different macroscopic lesions are described. Diagnosis needs a high index of suspicion, confirmed by histological examination, as it still can occur occasionally in immunocompetent persons. Response to specific treatment is good after diagnosis.

Diagnóstico patológico y molecular de un caso de tuberculosis laríngea primaria en un médico / Pathological and molecular diagnosis in a case of primary laryngeal tuberculosis in a physician

La tuberculosis laríngea primaria es una enfermedad rara con una amplia gama de manifestaciones clínicas. Se reporta el caso de un médico otorrinolaringólogo con diabetes de tipo II y con diagnóstico de tuberculosis laríngea primaria. El diagnóstico de cáncer de cuerda vocal se había considerado en otra institución, y al ingreso el paciente sólo presentaba disfonía de seis meses de evolución. En el estudio histopatológico se encontraron granulomas, células gigantes multinucleadas, fibrosis y necrosis, y en la tinción de Ziehl-Neelsen, bacilos ácido-alcohol resistentes. El cultivo del tejido de cuerda vocal para micobacterias y la PCR-IS6110 fueron positivos. La cepa de Mycobacterium tuberculosis demostró sensibilidad a todos los medicamentos de primera línea. Se inició tratamiento según la estrategia DOTS ( Directly Observed Treatment, Short -course ). Se discute la presentación clínica, los diagnósticos diferenciales, el abordaje diagnóstico y los factores de riesgo asociados y se hace una breve revisión de la literatura.

Primary laryngeal tuberculosis is a rare disease with a wide variety of clinical manifestations. We report the case of an ear-nose and throat diabetic physician with primary laryngeal tuberculosis. The diagnosis of laryngeal cancer had been considered before in another institution, and at the patient´s admission, he only presented dysphonia with a six-month evolution. The vocal cord histological examination showed granulomas, giant cells, fibrosis and necrosis, and the Ziehl-Neelsen staining showed acid-alcohol resistant bacilli. The culture from vocal cord tissue was positive for mycobacteria, and IS 6110 -PCR was positive too. The Mycobacterium tuberculosis strain was sensitive to first line drugs. Treatment using directly observed therapy short-course (DOTS) was initiated. Clinical presentation, differential diagnosis, diagnostic workup, associated risk factors and a brief literature revision are discussed in this article.

Tuberculosis pulmonar, esofágica y laríngea / Pulmonary, esophageal and laryngeal tuberculosis

Resumen La tuberculosis es una de las enfermedades que más ha impactado en la sociedad a nivel mundial siendo influenciada por la pandemia del VIH, los patrones migratorios y el uso de la medicación antituberculosa. La forma extrapulmonar es rara siendo más característica en los pacientes inmunocomprometidos, cuyas manifestaciones clínicas son inespecíficas, por lo que constituye un reto diagnósticopara los clínicos, en la mayoría de los casos retardando su detección y tratamiento. Se presenta el caso clínico de un paciente aparentemente inmunocompetente que consulta por cuadro de seis años de evolución de disfagia progresiva, pérdida de peso inexplicada, en quien se encontró compromiso por tuberculosis a nivel esofágico y laríngeo que explicaban los síntomas de ingreso, así como compromiso pulmonar sin clara sintomatología. Cuadro llamativo y de relevancia por su forma de presentación de alto riesgo de diseminación de la infección en un paciente sin inmunocompromiso. (Acta Med Colomb 2014; 39: 85-89).

Abstract Tuberculosis is one of the diseases that has more impacted the global society, being influenced by the HIV pandemic, migration patterns and the use of anti-TB drugs. Extrapulmonary tuberculosis is rare, being more characteristic in immunocompromised patients, whose clinical manifestations are nonspecific, thus constituting a diagnostic challenge for clinicians and in most cases delaying its detection and treatment. The case of a patient apparently immunocompetent consulting for a six years history of progressive dysphagia and unexplained weight loss, in whom involvement of esophagus and larynx by tuberculosis was found explaining the symptoms of admission, as well as the pulmonary involvement with no clear symptoms, is presented. It is a striking and relevant clinical picture by its presentation with high risk of dissemination of the infection in a patient without immunocompromise. (Acta Med Colomb 2014; 39: 85-89).

Tuberculosis of Larynx: A case report.

A case of tuberculosis of larynx in a 45-year-old male patient has been described here. Usually, the signs and symptoms of laryngeal tuberculosis resemble with malignant diseases of larynx. The diagnosis was made here by the microscopic examination of sputum smear for Acid Fast Bacilli, chest x-ray, direct laryngoscopy and biopsy from the laryngeal lesion.

The Current Clinical Propensity of Laryngeal Tuberculosis: Review of 60 Cases / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Although laryngeal tuberculosis is not common, it still occurs with an increasing incidence of pulmonary tuberculosis. The clinical pattern and spread mechanism of this disease have also changed as well. This study was performed to examine the current propensity seen in laryngeal tuberculosis and the clinical characteristics of this disease in patients showing atypical clinical pattern. SUBJECTS AND METHOD: We retrospectively analyzed 60 cases of laryngeal tuberculosis diagnosed from 1994 to 2004 in the department of otorhinolaryngology at Severance Hospital by evaluating clinical and videostroboscopic records. RESULTS: The age of the patients ranged from 25 to 78 years, with their average age being 49.7 years. The ratio between men and women was 1.9 : 1. The major symptom encountered was hoarseness (96.6%). Clinically, granulomatous (n=22) and ulcerative types (n=11) of laryngeal tuberculosis were still prevalent, however, the incidence of atypical types such as polypoid (n=16) and nonspecific (n=11) were on the rise. Among 27 cases that showed polypoid or nonspecific types, unilateral lesion was seen in 20 cases (74%). The most frequently affected area by this disease was true vocal cord, followed by false vocal cord, epiglottis, arytenoids and posterior commissure. Active pulmonary tuberculosis was present in 28 (46.7%), inactive pulmonary tuberculosis in 20 (33.3%), normal lung status in 12 cases (20%). Primary laryngeal tuberculosis was present in 9 cases (15%). Single lesion, polypoid and nonspecific type were the prevalent characteristics found in patients with inactive tuberculosis or normal lung status. CONCLUSION: Physicians should be aware of changes in the clinical pattern of laryngeal tuberculosis, which pose serious complications and risk of spreading.

A Case of Intestinal Tuberculosis Concurring with Endobronchial and Laryngeal Tuberculosis

Although the incidence of tuberculosis has been reduced recently because of the advance of anti-tuberculosis chemotherapy, improvements of public health, and early diagnosis, it is still high in developing countries. Intestinal tuberculosis can occur at any age, but young adults and female are more affected. Early diagnosis of childhood intestinal tuberculosis is difficult, largely because of vague symptoms and nonspecific signs. Recently, tuberculosis of the larynx combined with pulmonary tuberculosis has become quite a rare disease since anti-tuberculous chemotherapy and preventive activities are prevalent. Laryngeal tuberculosis, while relatively well recognized in the adult population, is a rare disease in chidren and adolescents. There are few reports of intestinal tuberculosis combined with endobronchial and laryngeal tuberculosis in children. We have experienced a case of intestinal tuberculosis which concurred with endobronchial and laryngeal tuberculosis in an 18-year-old girl who presented with abdominal pain, diarrhea, weight loss, a brassy cough, and anemia, which was diagnosed by a colonoscopy and bronchoscopy with biopsy.

Laryngeal tuberculosis.

Laryngeal tuberculosis has recently decreased in number and infectivity. To evaluate the changing patterns, we reviewed 14 patients who were diagnosed as laryngeal tuberculosis seen at Department of Otolaryngology, Siriraj Hospital, during the 5 year period, from 1 January 1982 to 31 December 1986. The results showed 10 male and 4 female patients, aged 34-84 years with an average of 58.7 years. The common presenting symptom was hoarsest of voice (52.6%), with a mean duration of 2.8 months. The most common site in the larynx was the vocal cord, in about 40% of the cases. The lesions were mass like lesions and there normal vocal cord movement in about 50%. Nearly all of the patients (92.9%) had pulmonary tuberculosis in their chest x-ray, but only a few had active or infective lesions in previous reports. The finding of acid fast bacilli in pathological section was 50%.

Concurrent Tuberculosis of the Larynx and the Tonsil

Tuberculosis of the larynx and the tonsil were not relatively uncommon diseases in the past, but they have become rare disease with the advent of effective antituberculous chemotherapy. Especially cases secondary to tuberculosis elsewhere in the body are indeed uncommon. We have recently seen a case of tuberculosis of the larynx associated with that of the tonsil which is thought to have developed secondary to miliary tuberculosis.
