Abstract:
We report the case of an adult with Crohn's disease and pulmonary sarcoidosis on the background of cystic fibrosis (CF). There is a recognized association between Crohn's colitis and CF, but cases of pulmonary sarcoidosis in CF are rare. There may be a pathogenic link between the two granulomatous disorders and CF with chronic immune stimulation leading to hyperimmunoglobulinemia, circulating immune complexes and subsequent granuloma formation.

Cystic Fibrosis: Pathogenesis
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

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.
