RESUMEN
Primary bronchial neoplasms in children, especially malignant lesions, are extremely rare. We report a case of a 10-year old boy with intermediate-grade mucoepidermoid carcinoma of the right intermediate bronchus, presenting as collapse and bronchiectasis after pneumonia. He was diagnosed by bronchoscopic biopsy. The lobectomy was performed. The patient is in good condition 1 year after operation. All reported cases of bronchial mucoepidermoid tumors in children had histologically low or intermediate grade(well differentiated) variety with a benign clinical course. The optimal surgical therapy for bronchial mucoepidermoid tumors is identical. There must be total removal of either mass with the sacrifice of as little normal lung as possible.
