Abstract:
Spread of Mycobacterium tuberculosis (MTB) to the larynx is exceedingly rare and can be obscured by more common conditions such as laryngeal cancer or oropharyngeal candidiasis, complicating an accurate diagnosis. Risk factors for chronic laryngeal disease, such as smoking and toxin exposure, place TB infection comparatively lower for consideration on a physician's differential. However, identifying these lesions is crucial from a medical and public health perspective to prevent community spread. We report the case of a 60-year-old male who presented with dysphonia, pharyngitis, aphasia, and significant unintentional weight loss. X-rays demonstrated focal opacities in the upper lung lobes. Laryngoscope biopsy revealed caseating granulomas and a positive culture for MTB. Laryngeal TB presents as a suspicious throat mass with nonspecific symptoms and should be thoroughly investigated by clinicians.

Pulmonary Tuberculosis II
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...

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis I
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.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
