Abstract:
Tuberculosis (TB) and sarcoidosis are multisystem, chronic granulomatous diseases. Although characterized by similar clinical manifestations, these disease entities vary significantly in etiologies and management. Sarcoidosis is an immunological disorder of unknown etiology, characterized by the presence of noncaseating granulomas in the tissues involved. TB is the infectious disease caused by Mycobacterium tuberculosis, characterized by granulomas with caseous necrosis. It is rare to have both the diseases concomitantly. We present the case of a 38-year-old male with microbiological confirmation of coexistent pulmonary TB and sarcoidosis.

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 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...
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.
