This newborn was noted to have widely disseminated crusted papules at virth. Some papules, like those on his left shoulder, were red and edematous. Skin biopsy of a papule showed dense aggregates of mast cells in the superficial and mid dermis. After the crusts healed a week later, it was easy to demonstrate a Darier sign, wheal and flare around papules that were rubbed by the examiner. This child had no symptoms, fed well, and was discharged from the nursery on the second day of life. The papules did not blister or form crusts again. The blanching red patch on the back of the neck was an innocent congenital vascular malformation.
