PG - e00200 LID - 10.1002/rcr2.200 [doi] LID - e00200 AB - A pulmonary lymphoepithelioma-like carcinoma (PLELC) is similar to a lymphoepithelioma, a subtype of nasopharyngeal carcinoma and commonly associated with Epstein-Barr virus infection which is a rare tumour and classified in the group of "other and unclassified carcinoma" in the latest 2015 World Health Organization (WHO) classification. Some reports of lymphoepithelioma-like carcinoma (LELC) have noted an epidermal growth factor receptor (EGFR) mutation, whereas none have noted a mutation of the echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) fusion gene. This is the first reported case of PLELC with ALK rearrangement. A 76-year-old woman underwent a right lower lobectomy and complicated partial resection of the upper lobe with lymph node dissection under complete thoracoscopic approach. A histopathological diagnosis of PLELC was made and the stage was classified as T1aN1(#12l) M0, pl0, G2, Ly1, V1. The results of both ALK immunohistochemistry and EML4-ALK fusion gene on fluorescence in situ hybridization (FISH) examinations were positive; however, EGFR mutational analysis results showed wild-type mutation.
