Prolonged cord separation in a newborn: a rare case of an unusual epithelialised umbilical cord.

A female full-term neonate, accompanied by her parents, was referred to the paediatric surgery department on the day of after birth. She presented with a 9 cm length pathological umbilical cord, of which the first 7 cm was red and wet, with ulceration, necrosis and healing areas. The patient never had a fever. Abdominal palpation showed no umbilical hernia and abdominal Doppler ultrasound was normal. After several days of disinfection, by biseptine antiseptic solution, and a monthly follow-up, most of the umbilical cord fell out. It only remained a 4 cm length navel consisting of 2 cm of excessive skin and 2 cm of mucous tissue. The lesion was surgically excised at 6 months old. The patient was discharged on postoperative day 1. The results of the histology confirmed the diagnosis of an epithelialised umbilical cord. The 1-month follow-up was uneventful.
