•benign; very common
•usually arises in the first two days of life
•resolves spontaneously within 10 days

•affects all body surfaces except palms and soles (vs. neonatal scabies)
•Tzank --> eosinophils
•ddx: neonatal HSV, transient neonatal pustular melanosis, neonatal scabies
•see also Vesicles and Pustules in a Newborn ddx
