Primary isolated laryngeal tuberculosis: A rare extrapulmonary manifestation

Area of Science:

• Otorhinolaryngology
• Infectious Diseases
• Pulmonology

Background:

• Laryngeal tuberculosis (TB) is an uncommon extrapulmonary form of TB.
• Isolated laryngeal TB, without concurrent pulmonary disease, is exceptionally rare.
• Nonspecific symptoms like hoarseness, throat pain, and dysphagia present diagnostic challenges.

Observation:

• A 42-year-old female presented with a persistent change in voice.
• Initial symptoms were limited to vocal changes, without other signs of active TB.
• Investigations led to the diagnosis of isolated primary laryngeal tuberculosis.

Findings:

• The patient was diagnosed with isolated primary laryngeal tuberculosis.
• The diagnosis was confirmed after thorough investigations.
• The case underscores the varied presentations of extrapulmonary TB.

Implications:

• Highlights the importance of considering rare diagnoses in cases of persistent hoarseness.
• Emphasizes the need for comprehensive diagnostic workups for suspected laryngeal TB.
• Contributes to understanding the clinical spectrum of laryngeal tuberculosis.
