Abstract:
We report a case of pulmonary blastomycosis appearing as metastatic laryngeal squamous cell carcinoma. Pulmonary blastomycosis was discovered as right lower lobe subpleural activity consistent with metastatic disease on a positron emission tomographic (PET) scan following total laryngectomy and bilateral neck dissection for locally invasive laryngeal squamous cell carcinoma. A computed tomographic (CT) scan of the chest showed a right lower lobe, subpleural pulmonary nodule. CT-guided fine-needle aspiration of the nodule revealed broad-based budding yeast consistent with blastomycosis. To our knowledge, this is the first case of a PET-positive pulmonary blastomycosis lesion mimicking pulmonary malignancy reported in the literature.

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.
