Abstract
Congenital mature teratomas of the umbilical cord are extremely rare. We report on a girl who presented with a ruptured omphalocele and a 7 cm mass connected to the umbilicus, which we resected on the first day of life. Histology revealed mature umbilical cord teratoma . On the 29th day of life, a secondary laparotomy was necessary to address the associated intestinal malformations (megaduodenum, stenotic small bowel with duplication and malrotation). After a prolonged hospital stay, we discharged the patient in age-appropriate conditions. Antenatal diagnosis of an umbilical cord tumor can be challenging in the presence of an omphalocele. Given the high prevalence of associated malformations, the finding of umbilical cord teratoma should be followed by a detailed and comprehensive neonatal workup for additional abnormalities.
Highlights
Teratomas can be subgrouped into extragonadal and gonadal
Umbilical cord teratoma (UCT) was first described in 1878 by Budin in a full-term female newborn with a mass as big as an “adults’ fist.”[4]. We present a female neonate with a ruptured omphalocele and an umbilical mass which turned out to be an UCT
In UCT, there is a female predominance with 14 female, two male, and two cases of unknown gender
Summary
Teratomas can be subgrouped into extragonadal and gonadal. Two-thirds of these tumors are extragonadal and onethird is of gonadal origin.[1]. We took the child to the operating room for explorative laparotomy on the first day of life. During this procedure, the mass was carefully separated from the adherent small bowel and resected (►Fig. 1B). A third laparotomy on the 67th day of life was necessary due to a functional stenosis between the tubularized duodenum and the jejunum. The 4th laparotomy on the 134th day of life was necessary to remove the two masses close to the pancreas (2 and 1.5 cm in diameter on magnetic resonance imaging [MRI). At this time, the length of the small bowel was 80 cm. After a follow-up of 23 months, the girl has no developmental deficits and no signs of a tumor recurrence on MRI or elevated tumor markers (AFP or β-hCG)
