Abstract:
We report a rare case of nonmucinous pulmonary micropapillary adenocarcinoma mimicking pulmonary tuberculosis. A 68-year-old woman was hospitalized with hemoptysis. Her computed tomography revealed cavities and tree-in-bud appearance similar to the extensive form of pulmonary tuberculosis. However, histopathological findings of transbronchial biopsies of all lesions revealed adenocarcinoma and no pulmonary tuberculosis. Tree-in-bud appearance may relate to the floating micropapillary tufts in alveolar spaces. If pulmonary carcinoma is complicated by pulmonary tuberculosis, patients must be isolated and disadvantaged in cancer treatments. Therefore, recognizing this case may be therapeutically useful for respiratory physicians treating both diseases.

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...

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.
