Abstract:
A 65-year-old female smoker was admitted due to haemoptysis and a pulmonary infiltrate in the right lower lung lobe. Tumour was suspected, but there was also a history of 2 years spent in Arizona, known to be endemic for the dimorphic fungus Coccidioides immitis. IgG antibodies and airway culture for C. immitis were negative, and surgery was performed for suspected lung cancer. No malignancy was detected at histopathological investigation, but typical coccidioidal spherulae were observed by silver stain. Coccidioidoma may be a differential diagnosis to malignant tumour in individuals visiting endemic areas.

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

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.
