A bronchial adenoma is a glandular tumor in the trachea or large bronchi (the large airways of the lung) that usually causes obstruction of the airway. Although the term bronchial adenoma classically refers to a benign tumor of the airway, also known as a mucous gland adenoma, it is often misapplied to malignant tumors such as carcinomas and carcinoids of the airways.

Causes, incidence, and risk factors
These tumors grow slowly and rarely metastasize (spread). The cause is unknown. There is a tendency of this type of tumor to cause bleeding or obstruction of a lung or lung lobe.


bloody sputum



recurrent pneumonia

slowly resolving pneumonia

collapse of a lung lobe or segment

cough lasting more than 6 weeks.

Additional symptoms that may be associated with this disease:

skin blushing/flushing (see carcinoid syndrome)

Signs and tests


chest X-ray may show a single lung nodule or pneumonia in one segment or lobe of the lung

Surgical or endoscopic removal of the tumor is the standard treatment.

Expectations (prognosis)
Surgery usually results in a complete cure.



airway obstruction


spreading of the tumor to regional lymph nodes (very rare)
