Most common symptom of bronchial adenoma is -

• Centrally located slow-growing endobronchial lesions that are generally carcinoid tumors (80%), adenocystic tumors (so called cylindromas, 10–15%), or mucoepidermoid tumors (2–3%). • Mean age at presentation is 45 years (range 15–60). Clinical Features • MC symptom: Recurrent Hemoptysis • History of chronic cough, intermittent hemoptysis, or repeated episodes of airway obstruction with atelectasis, or pneumonias with abscess formation due to endobronchial lesions obstructing the airway. Diagnosis • Usually visible at bronchoscopy but are highly vascular and may bleed profusely after a bronchoscopic biopsy. Treatment • They are largely curable by surgical resection (local excision), but they may recur locally or become invasive and metastasize. • Five-year survival after resection is 95% for localized disease.
