Primary lymphoepithelioma-like carcinoma of the lung.
Lymphoepithelioma is an undifferentiated carcinoma with prominent lymphoid stroma in the nasopharynx. Tumors with similar histology have been reported with other localizations, including the lungs, and are designated as lymphoepithelioma-like carcinomas (LELC). Primary LELC of the lung is very rare, and scant information is available in the scientific literature. This paper details the case of a 25-year-old Caucasian male patient with the diagnosis (determined by thoracotomy) of primary LELC of the lung. Immunohistochemical analysis was negative for Epstein-Barr virus, as was the in situ hybridization of the tumor cells. Observation of the nasopharynx and a magnetic resonance image of the cavum were normal. Because the tumor (T4N2M0) could not be resected, the patient was treated with chemotherapy, carboplatin/5-fluorouracil, completing two cycles. The patient's condition worsened when he developed contralateral pneumonia, which was then followed by pericardial effusion. The patient died 36 h later from cardiac tamponade. Presented here is a revision of this rare pathology, not often reported in the literature.
