Abstract:
We present an atypical case of tuberculosis in an immunocompetent man from west Africa living in Europe. The patient entered the hospital with a painful lump of 3 cm on his right clavicule which he noticed 2 weeks before and back pain. During the examinations for further evaluation his condition deteriorated within short time. Tuberculosis was diagnosed, treatment started but he needed mechanical ventilation at the intensive care unit and had kidney failure. The further evolvement was favourable in the end but needed intensive treatment for over 4 weeks. Tuberculosis cases with such severe evolution are rather known with immunodeficient patients. Extrapulmonary tuberculosis, especially skeletal tuberculosis is seen more frequent in young immunocompetent migrants. The migrating persons seem to be more at risk to get sick than the ones staying in their origin country. We suppose the course of our patient's disease is miliary or septic, of which both are rather rare entities.

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 III
The first classification is based on the development of the disease, and it includes the following categories:
Atypical Pneumonia
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.

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...
