A 6-month-old infant was brought for evaluation of an "atypical mole" on the chest that her parents and referring physician feared might be skin cancer. The parents reported that the lesion had been present since shortly after birth and had become red and inflamed after minor trauma on a few occasions and once had blistered.

A 2-year-old boy was brought for evaluation of a rash and fever of 2 days' duration. He had atopic dermatitis since 6 months of age that was partially controlled with low-potency topical corticosteroids and emollients. His father reported that recently the facial dermatitis had worsened, with increased redness, pain, and some skin breakdown. The child's medical history was otherwise unremarkable. His mother had a history of "cold sores."
