Anaplastic Lymphoma Kinase Inhibitor in Treatment of Inflammatory Myofibroblastic Tumor of the Tongue in Infancy.

Inflammatory myofibroblastic tumors (IMTs) are rare in neonates. IMTs of the tongue are also very rare in infancy, with only 1 case reported in this age group. The mainstay of therapy has traditionally been surgery, which can be devastating to surrounding structures and negatively impact prognosis. Approximately 50% of IMTs harbor a translocation involving the anaplastic lymphoma kinase gene. We describe a case of IMT of the tongue in a neonate treated with debulking and an anaplastic lymphoma kinase inhibitor. The patient achieved complete response and remains disease-free 1.5 year following completion of therapy.
