The umbilicus is perhaps the only scar that all of us want. The umbilicus forms after birth as a result of the placental cord being transected as the infant is “detached” from his/her mother. As the stump of the cord necroses, the scab falls away as the base heals leaving a scar: the umbilicus.
The umbilicus has been described as a depressed scar surrounded by a natural skin fold that measures 1.5 to 2 cm in diameter and lies anatomically within the midline at the level of superior iliac crest.
