Abstract:
We report a case of fatal pulmonary infection caused by Mycobacterium abscessus in a middle-aged patient with acquired esophago-pulmonary fistula which contributed to repeated exacerbation. Acquired benign esophago-pulmonary fistula is uncommon. After a 55-year-old woman was diagnosed with pulmonary Mycobacterium avium disease in 1989 and improved with multidrug chemotherapy, she developed pulmonary M. abscessus in 2001. Despite multi-drug treatment, she suffered repeated exacerbation and her condition gradually deteriorated. Chest computed tomography (CT) showed esophago-pulmonary fistula which was comfermed by esophagoscopy. An M. abscess infection may give rise to adhesions between the tracheobronchial lymph nodes and the neighboring esophagus, with subsequent development of a traction diverticulum which may extend to the tracheobronchial tree. In the present case, aspiration of liquids through the fistula induced a cough reflex, and M. abscessus spread through the airway. It might be possible that esophago-pulmonary fistula is not only a complication of pulmonary M. abscessus infection but also an exacerbation factor.

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...

Clinical Manifestations:
Chronic Obstructive Pulmonary Disease II: Emphysema
Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

The first classification is based on the development of the disease, and it includes the following categories:
