Primary tuberculosis of the larynx

Area of Science:

• Infectious Diseases
• Otolaryngology
• Pulmonology

Background:

• Tuberculosis (TB) is a chronic bacterial infection caused by Mycobacterium tuberculosis.
• While typically affecting the lungs, rare cases of isolated laryngeal tuberculosis occur.
• Laryngeal TB presents with variable and often misleading clinical and endoscopic features.

Purpose of the Study:

• To highlight the importance of considering laryngeal tuberculosis in differential diagnoses.
• To emphasize the effectiveness of medical treatment for laryngeal TB.
• To describe the epidemiology, clinical presentation, and management of laryngeal TB.

Main Methods:

• Retrospective study of ten laryngeal tuberculosis cases (2004-2009).
• Review of literature on primary laryngeal tuberculosis in endemic areas.
• Analysis of epidemiology, clinical findings, investigations, and treatment outcomes.

Main Results:

• Laryngeal TB primarily affected male smokers and drinkers in this series.
• Clinical and endoscopic signs were non-specific, resembling laryngeal cancer.
• Diagnosis was confirmed solely by bacteriological and histological examinations.
• Antituberculosis chemotherapy (≥6 months) yielded excellent short-term and long-term results.

Conclusions:

• Findings correlate with existing literature on laryngeal tuberculosis.
• Non-specific laryngeal signs necessitate considering TB diagnosis.
• Prompt bacteriological and histological confirmation is essential for appropriate management.
