Abstract

A 30-year-old woman applied to our hospital because of back pain. Total atelectasis was seen in the left hemithorax at the chest X-ray. Computed tomography (CT) revealed decreased left lung volume and mediastinum deviated to the left hemithorax. Bronchoscopy showed concentric stenosis in the left main bronchus. According to these find­ings, left thoracotomy and pneumonectomy were performed. Patho­logic diagnosis was lymphoepithelioma-like carcinoma.Lymphoepithelioma-like carcinoma is an undifferentiated carcinoma that shows prominent lymphoid infiltration within the fibrous stroma. It is commonly seen in the nasopharynx. Most recently it was diagnosed as a primary lung tumor.
