Abstract:
Prurigo nodularis (PN) is a rare chronic skin disorder of unknown origin. Here we describe what is believed to be the first case of PN associated with tuberculosis. For the first time, culture and PCR analysis of skin biopsy confirmed the presence of Mycobacterium tuberculosis complex in PN skin lesions. The pruritus and skin lesions resolved following antitubercular therapy. Our case provides further evidence in favour of a link between PN and mycobacterial infection.

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.
