Abstract
We have experienced two young patients of high grade malignancy mucoepidermoid carcinoma (High-grade MEC) which is reported to be rare. Case 1, a 31-years-old man with abnormal shadow on chest X-ray underwent left upper lobectomy. Case 2, a 37-years-old man with high fever was visited to our hospital. Atelectasis of the left upper lobe was found and complete obstruction of the left upper lobe found by bronchoscopy. Sleeve left upper lobectomy was performed. Preoperative diagnoses of both two patients were adenocarcinomas and postoperative histological examination revealed High-grade MECs with N2. After operation, both two patents had recurrence soon and died.
