Plastic bronchitis is an extremely rare disease characterized by the formation of tracheobronchial airway casts, which are composed of a fibrinous exudate with rubber-like consistency and cause respiratory distress as a result of severe airflow obstruction.

The thought of mucus disturbs many people. Mucus is beneficial as the first defense of the airways. The mucus lining traps inhaled particles and allows them to be cleared from the airway by cilia and cough. The mucus layer also prevents dehydration and desiccation of the airway surface and provides a nutrient milieu for the ciliated epithelium. Mucus can also be quite bad. Airway mucus retention due to hypersecretion or poor mucus clearance is a characteristic of many airway diseases including cystic fibrosis, chronic bronchitis, bronchiectasis, and asthma.

Bronchial Adenomas Bronchial adenomas (80% are central) are slow-growing endobronchial lesions; they represent 50% of all benign pulmonary neoplasms. About 80–90% are carcinoids, 10–15% are adenocystic tumors (or cylindromas), and 2–3% are mucoepidermoid tumors. Adenomas present in patients 15–60 years old (average age 45) as endobronchial lesions and are often symptomatic for several years. Patients may have a chronic cough, recurrent hemoptysis, or obstruction with atelectasis, lobar collapse, or pneumonitis and abscess formation.
