Abstract:
It is known that Histoplasma capsulatum can cause chronic granulomatous disease or fibrosing mediastinitis, but both presentations occurring in the same patient is exceedingly rare and difficult to diagnose. The patient is a 24-year-old female with a past medical history of asthma, who presented for worsening shortness of breath. Thoracic imaging revealed a large paratracheal mass with a significant mass effect. Endobronchial ultrasound (EBUS) was attempted unsuccessfully, and the patient underwent video-assisted thoracoscopic surgery, which established the diagnosis of fibrosing mediastinitis. Extensive infectious disease workup confirmed Histoplasma infection. She was treated with a course of Itraconazole, pulmonary artery stenting, and rituximab.

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.
