Anaplastic lymphoma kinase (ALK) rearrangement has also been reported in non-small cell lung carcinomas, such as Echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) fusion identified in a lung adenocarcinoma metastasis to the thyroid [12]. The gene discussed is ALK; the disease is lung adenocarcinoma.
