Abstract:
A 54-year-old man with a history of smoking developed infectious bullae at the apex of his left lung and underwent long-term antimicrobial treatment. The bullae gradually reduced in size along with a slight left pleural thickening. Left back pain relapsed after a year, and CT revealed a rapid increase in pleural thickening. Left upper lobectomy led to the diagnosis of pulmonary polymorphic carcinoma. Chronic inflammation due to infection could contribute to carcinogenesis; therefore, post-inflammatory changes should be carefully followed-up.

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:
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.

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
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...
