title: Primary polymorphous low-grade adenocarcinoma of the bronchus: complete tumor removal with bronchoscopic resection.
abstract: Primary polymorphous low-grade adenocarcinoma (PLGA) is an uncommon malignant tumor arising from the minor salivary glands, but its occurrence as a primary tumor of the tracheobronchial tree is very rare. Herein, we have reported a rare case of endobronchial PLGA in a 56-year-old woman presenting with chronic cough and progressive exertional dyspnea. Chest CT clearly demonstrated an endobronchial tumor obstructing the distal part and bifurcation of the left main bronchus and causing distal atelectasis. She underwent rigid bronchoscope with electrocautery and bronchoscopic resection of the tumor. PLGA was diagnosed histologically. Subsequent left pneumonectomy was performed and showed no evidence of residual tumor.
