For 2018 the American Cáncer Society reports 234.030 new cases of lung cáncer, 154.050 people will die from this cause, the average age of diagnosis is approximately 70 years old. Lung cáncer in children and adolescents is extremely rare, in Colombia the incidence in children under 18 is less than 1%. The 85% of lung cancers are classified as non-small cell lung cáncer, there are recent advances in treatment with Anaplastic lymphoma kinase (ALK) inhibitors Crizotinib, Alectinib, Brigatinib for non-small cell lung cáncer ALK positive. This case report is from a 14-year-old adolescent patient treated in our institution with an ALK inhibitor.
