Mucus gland adenoma of the bronchus

Mucus gland adenoma of the bronchus is a rare lesion which should be clearly differentiated from carcinoid and cylindromatous adenomas. Characteristically, the tumor projects into the lumen of the bronchus as a polypoid mass. Although it can cause obstruction and hemoptysis, it does not invade bronchial tissues or metastasize. The case described in this report is typical of mucus gland adenoma. The involved lung lobe was excised, and the patient was discharged after an uncomplicated postoperative course.
