Summary
Tuberculosis of the larynx and pharynx is rare but increasing. This case highlights isolated laryngo-pharyngeal tuberculosis in a pregnant woman, emphasizing early diagnosis of uncommon upper airway lesions.
Area of Science:
- Infectious Diseases
- Otolaryngology
- Public Health
Background:
- Tuberculosis (TB) incidence is rising globally.
- Laryngeal and pharyngeal TB are uncommon presentations.
- Increased TB cases raise the possibility of isolated upper airway lesions.
Observation:
- A 30-year-old immunocompetent pregnant female presented with odynophagia.
- Symptoms persisted for ten months without respiratory or systemic signs.
- An oro-pharyngeal granulomatous lesion was identified.
Findings:
- Biopsy confirmed acid-fast bacilli, indicative of tuberculosis.
- No clinical or radiological evidence of pulmonary TB was found.
- The patient successfully completed a nine-month TB treatment protocol.
Implications:
- Highlights the importance of considering TB in unusual upper airway presentations.
- Underscores the need for heightened clinical suspicion for early diagnosis.
- Relevant for infectious disease specialists, otolaryngologists, and public health officials.

01:28Pulmonary Tuberculosis II
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

01:23Tuberculosis
Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:28Pulmonary Tuberculosis V
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
