**6. Congenital hernia of the umbilical cord**

Congenital hernia of the umbilical cord (CHUC) is a rare congenital entity recognized as a distinct entity since the 1920s but is often misdiagnosed as a small omphalocele. During the first 5th–6th week of gestation, the bowel herniates into the developing umbilical cord and withdraws into the abdominal cavity until the 10th–12th week of gestation [60]. Return of

A review of the literature described associated malformations like pulmonary stenosis, cleft lip and palate, ear tag, small and large bowel atresia and stenosis, short bowel syndrome, tetralogy of Fallot, Meckel's diverticulum, persistent cloaca, and congenital glaucoma [61] (**Figure 10**).
