A case of full-thickness pressure necrosis of the scalp in a newborn is reported. This is a rare injury, with only four similar prior reports found in the literature. The presumed mechanism of injury is pressure of the infant's head against the mother's bony pelvis. A spectrum of injury can be seen, from temporary alopecia to complete scalp necrosis. Risk factors include prolonged ruptured membranes and prolonged labor.
