ABSTRACT

A 43-year-old woman was admitted to our hospital because of a nodule in the right middle lobe of her lung. Transbronchial biopsy detected only non-caseating epithelioid cell granulomas. Strongly suspecting the nodule to be lung cancer, we subsequently performed video-assisted thoracoscopic surgery. The final diagnosis was lymphoepithelioma-like carcinoma (LELC) of the lung with granulomatous lesions inside the tumor. Because various disorders cause granulomas, further investigation should be considered when pathological findings are inconsistent with the clinical course.
