Rare Birth Defects in Pregnancies of Women with Pregestational Diabetes: Absent Radius

Diabetes mellitus (DM) is an important disease that negatively affects fetal development and women with pregestational diabetes have an increased risk for adverse pregnancy outcomes, including a markedly increased risk for birth defects. In this report, a newborn with absent radius associated with pregestational diabetes was presented. A male newborn was born at 40th gestational week from a 20-year-old mother by cesarean section. The patient had shortness in the limbs, hypoplastic right thumb and flexion contracture at his right hand besides respiratory distress.To our knowledge, with this case report, we would like to share the second case of diabetic mother’s infant with absent radius in the literature.
