Abstract:
Laryngeal tuberculosis is a rare entity and the disease related to laryngeal cancer is extremely rare. We describe a case of laryngeal tuberculosis in a 74-year-old man with a history of radiotherapy for laryngeal carcinoma four months earlier. Laryngoscopy demonstrated a white mass on the right vocal fold at the site carcinoma had previously occupied. Recurrence of the cancer was suspected, but the biopsy result showed histological features of tuberculosis. We discuss the derangement of the host's mucosal barrier by the malignancy as a contributing factor in secondary tuberculous infection. Tubercular bacilli may be reactivated due to the immunosuppression associated with the therapy.

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...
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.

Pulmonary Tuberculosis V
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...
