Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is a rare malignant tumour with histological features similar to undifferentiated nasopharyngeal carcinoma. A close association is known to exist between pulmonary LELC and Epstein-Barr virus infection in Southeast Asian countries. We report a 69-year-old man with pulmonary LELC arising from a thin-walled cavity with a smooth inner surface and characterized by an unexpectedly rapid progression.
