We report a case of mucoepidermoid carcinoma of the trachea in a 23-year-ol d pregnant female in her 39th week. The patient had cough and wheezing in t he early morning for 9 months before admission. No abnormalities were detec ted on a chest roentgenogram. At Caesarean section, fiberscopy revealed a p olypoid lesion narrowing the trachea. The pathologic diagnosis mane from th e biopsy specimen obtained was low-grade mucoepidermoid carcinoma and the l esion was resected. Airway hyperresponsiveness was shown before resection w ith airflow limitation however, airway reactivity and airflow limitation im proved 1 year after resection.
