Tyrosine kinase inhibitors (TKIs) are rarely used in pregnancy. There is almost no information on the effect of recently developed TKIs on the fetus. Case Report: A 22-year-old woman became pregnant while using radotinib, a novel TKI for CML. She was concerned about the possible teratogenic effect of radotinib; hence the first pregnancy was terminated. The patient underwent full-term delivery at the second pregnancy. The infant had facial deformity and congenital laryngomalacia. Conclusion: We witnessed structural abnormality when the patient used radotinib during the first trimester of pregnancy. When radotinib is prescribed for women of childbearing age, thorough education about contraception is necessary.
