Abstract:
We herein report a rare case of diffuse pulmonary metastasis occurring approximately one year after surgical excision of cutaneous squamous cell carcinoma that had been thought to be stage I with a free margin of healthy tissue. In addition, this case had chest imaging findings unusual for a skin cancer patient, showing a miliary pattern on computed tomography (CT). Distant metastases may develop even if early-stage cutaneous squamous cell carcinoma is completely resected. When observing a miliary shadow on chest CT, metastatic lung tumor from skin cancer should be considered as a differential diagnosis.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
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.

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 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...
