Mucoepidermoid carcinoma of the tracheobronchial tree, which is thought to arise from the minor salivary gland tissue of the proximal airway, is an extremely rare neoplasm. We herein report a case of a 31-year-old pregnant woman in her 36th week, who complained of recurrent hemoptysis from bronchial mucoepidermoid carcinoma. As massive bleeding from the tumor was seen during a caesarean section, it was necessary to add bronchial artery embolization. The tumor was successfully removed by a sleeve resection of the left main bronchus after the embolization. The patient is doing well without any signs of recurrence at 3 years after undergoing the operation.
