Background: Mucoepidermoid carcinoma (MEC) is a rare malignancy in lung. Surgical resection is considered as a standard treatment surgical outcomes have been reported in small series. To investigate clinical characteristics, bronchoscopic findings and the role of bronchoscopic interventions, retrospective review was performed. Methods: Medical records were collected in Samsung Medical Center between January 1997 and December 2011. Clinical features, bronchoscopic findings, treatment modalities and treatment outcomes were retrospectively analyzed. Results: Thirty seven patients were included in this study including 21 males (57%) with median age 41 years. Seventy percent of patients had one or more symptoms due to airway obstruction and bleeding. Most frequent bronchoscopic finding was exophytic mass (88%) with sessile stalk (76%) covered by normal mucosa. Bronchoscopic interventions were performed 7 patients (19%) to relieve airway obstruction and 34 patients (92%) underwent surgical treatment. Five year overall survival was 86% and favorable factors for long term survival were low grade histology and early clinical stage. Conclusion: The MEC shows exophytic endobronchial mass in tracheobronchial tree and good clinical outcome after complete resection.
