The pediatric dermatology team was called to the neonatal intensive care unit to evaluate a full-term male newborn with diffuse erosions present at birth. On examination, 1- to 4-mm simple erosions were noted over the scalp, face, trunk, scrotum, limbs, palms, and soles (Figure, A). Vital signs and findings from the remainder of the physical examination were normal.
The patient’s mother had a normal pregnancy. She was immune to rubella; negative for hepatitis B, human immunodeficiency virus, group B streptococcus, and syphilis; and had no history of genital herpes. She reported exposure to a relative who had chicken pox during the first trimester of her pregnancy.
