Laryngeal tuberculosis, a granulomatous disease, presents differently today, often mimicking other conditions. Suspect it in chronic laryngitis cases, especially with risk factors like immunodeficiency.

Area of Science:

  • Otorhinolaryngology
  • Infectious Diseases
  • Pulmonology

Background:

  • Laryngeal tuberculosis (LTB) is the most common granulomatous laryngeal disease.
  • Historically secondary to pulmonary tuberculosis, recent studies suggest up to 20% primary LTB.
  • Significant changes observed in LTB's clinical presentation, age of onset, and lesion type.

Purpose of the Study:

  • To describe the evolving characteristics of laryngeal tuberculosis.
  • To highlight diagnostic challenges and clinical suspicion criteria for LTB.

Main Methods:

  • Review of recent clinical observations and studies on laryngeal tuberculosis.
  • Analysis of epidemiological data, risk factors, and symptomatic presentation.
  • Comparison of historical and current macroscopic lesion appearances.

Main Results:

  • Laryngeal tuberculosis now presents in a wider age range, typically 41-50 years.
  • Key risk factors include tobacco use, alcohol consumption, malnutrition, and immunodeficiency.
  • Dysphonia (90%) and odynophagia (45%) are predominant symptoms.
  • Current lesions are often diffuse edema or pseudo-tumoral, unlike historical ulcero-infiltrative types.
  • Lesions can appear in any laryngeal zone, not just the posterior.

Conclusions:

  • Laryngeal tuberculosis exhibits altered clinical behavior and macroscopic findings.
  • Non-specific chronic laryngitis with poor evolution warrants suspicion for LTB.
  • Increased awareness of these changes is crucial for timely diagnosis and treatment.
