An 18-year-old woman was admitted to our hospital with hemoptysis and abnormal shadow on chest X-ray.
Chest X-ray film revealed complete atelectasis of the left lower lobe. Bronchoscopic examination showed complete obstruction of the left lower lobe bronchus by a polypoid tumor. Biopsied specimen of the tumor was diagnosed as a low-grade malignant mucoepidermoid carcinoma. Left lower lobectomy with bronchoplasty was performed. The polypoid tumor was 20×13 mm in size and protruded from the bronchial wall into the orifice of left B6. Postoperative histological examination revealed no metastases in the mediastinal lymphnodes. The postoperative course was uneventful. One year and 6 months has passed with no evidence of recurrence. The clinical and pathological features of 29 cases of mucoepidermoid carcinoma under the age of 40 years reported in the Japanese literature were reviewed.
