Rare Case of Exomphalos Complicated with Umbilical Cord Teratoma in a Fetus with Trisomy 13

Abstract

An exomphalos containing unusual solid and cystic mass was diagnosed during a routine ultrasound examination in the 17th week of gestation. Further investigations were planned but the pregnancy was terminated. The fetopathological examination revealed an umbilical cord teratoma. Although this entity is very rare it should be emphasized as a possible differential diagnosis when cystic lesion of the cord is detected. Large teratomas associated with abdominal wall defect may have poor fetal outcome and can be associated with structural and chromosomal abnormalities. In our case trisomy 13 was diagnosed.
