Laryngeal tuberculosis diagnosed by stool sample cultures: a case report

Mycobacterium tuberculosis Resides in Macrophages in Laryngeal Tuberculosis: A Case Report

Laryngeal tuberculosis is a rare form of extrapulmonary tuberculosis that questions the natural history of this infection. We report one such case in which a pathological examination of a laryngeal biopsy revealed granulomatous inflammation with caseous necrosis. Further investigations combining immunofluorescence detection of macrophages and in situ hybridization of Mycobacterium tuberculosis indicated the presence of Mycobacterium tuberculosis (M. tuberculosis) in laryngeal granulomatous inflammatory lesions. This observation suggests that the natural history of laryngeal tuberculosis does not differ from that of other forms, guiding early diagnosis in patients with laryngeal lesions to ensure appropriate check-ups and treatment.

Navigating the Complexities of Laryngeal Tuberculosis: A Comprehensive Case Report and Literature Review

This case report and literature review presents a detailed exploration of the diagnosis and management of laryngeal tuberculosis, emphasizing the challenges encountered in dealing with rare and multifaceted medical conditions. Through a systematic analysis of the patient's clinical journey and an insightful review of pertinent literature, the study underscores the complexity inherent in diagnosing primary laryngeal tuberculosis and highlights the growing relevance of this rare extrapulmonary manifestation. The case showcases the significance of a comprehensive diagnostic approach, the collaboration of diverse medical specialists, adherence to established treatment guidelines, and the crucial role of continuous patient monitoring. The successful resolution of this intricate case serves as a compelling testament to the power of interdisciplinary coordination and precision medicine, providing valuable insights into navigating the intricate landscape of laryngeal tuberculosis.

Mycobacterial identification on homogenised biopsy facilitates the early diagnosis and treatment of laryngeal tuberculosis

Introduction

The incidence of laryngeal tuberculosis has increased gradually in recent years. Laryngeal tuberculosis has strong infectivity and atypical clinical manifestations. Hence, establishing the early diagnosis of laryngeal tuberculosis is considered difficult, resulting in the high rate of misdiagnosis of laryngeal tuberculosis and increased rates of tuberculosis infection.

Objective

This study aimed to describe a case of laryngeal tuberculosis detected using the mycobacteria gene chips technology, facilitating the early diagnosis and the treatment of laryngeal tuberculosis.

Case presentation

A 27-year-old woman presented with a 7-day history of hoarseness, with a normal routine blood chemistry test and chest computed tomography results. Histological analysis of the vocal cord biopsy showed granulomatous inflammation and the negative acid-fast stain test. The mycobacteria gene chips method was used to directly examine the vocal cord tissue treated with homogenate, and the Mycobacterium tuberculosis was successfully identified. Thus, the early diagnosis of laryngeal tuberculosis and the drug sensitivity of rifampin and isoniazid were confirmed. The patient recovered after undergoing a 1-year standard anti-tuberculosis therapy.

Conclusions

Mycobacterial identification on homogenised biopsy using the mycobacteria gene chips method significantly facilitates the early diagnosis and the treatment of tuberculosis.

Malaria, tuberculosis and HIV: what's new? Contribution of the Institut Hospitalo-Universitaire Méditerranée Infection in updated data

The Institut Hospitalo-Universitaire Méditerranée Infection is positioned for the diagnosis, prevention and treatment of the ‘big three’ killer diseases: malaria, tuberculosis and HIV. We implemented the use of new diagnostic samples such as stools and new diagnostic tests such as mass spectrometry for the dual identification of vectors and pathogens. Furthermore, advances in the prevention and treatment of malaria and tuberculosis are reviewed, along with advances in the understanding of the role of microbiota in the resistance to HIV infection. These achievements represent a major step towards a better management of the ‘big three’ diseases worldwide.
