Abstract:
Pulmonary tumorlets occur as the result of extensive scar caused by bronchiectasis or other inflammatory processes. They are minute lesions found in close association with the bronchioles and may rarely metastasize to lymph nodes. We present a 35-year-old male patient who underwent bilobectomy inferior with a diagnosis of bronchiectasis of 20 years duration. Histologic examination showed cystic bronchiectasis with areas of multiple neuro-endocrine tumorlets in addition to metastatic peribronchial lymph nodes. We emphasize the significance of early surgical treatment of bronchiectasis showing little to no response to medical therapy as well as peribronchial lymph node dissection.

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:
Metastasis
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
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.
