This report describes a case of lung adenocarcinoma harboring an echinoderm microtubule-associated protein-like 4–anaplastic lymphoma kinase (EML4–ALK) fusion, high programmed death-ligand 1 (PD-L1) expression, and a Bcl-2-like protein 11 (BIM) deletion polymorphism. Here, EML4 is linked to lung adenocarcinoma.
