Abstract
A 15-year-old female consulted our hospital with chief complaints of cough and hemoptysis. After admission, those symptoms became aggravated, and the chest CT revealed complete atelectasis of the left lung and the presence of a tumor, 3cm in diameter, in the left lower lobe. Due to a large amount of the airway hemorrhage, both an intubation into the right main bronchus and an embolization of the bronchial artery feeding the tumor were performed. Then, we performed a left lower lobectomy. The tumor was pathologically diagnosed as low-grade malignant mucoepidermoid carcinoma. Although mucoepidermoid carcinoma is a hemorrhagic tumor, a large amount of hemorrhage in the respiratory tract requiring endotracheal intubation or vascular embolization is very rare.
