The classic lesion is a 2–3-mm elliptical vesicle surrounded by erythema, commonly described as a
“dew drop on a rose petal.” This quickly converts into a pustule, then umbilicates and crusts. The crust falls
off in 1–3 weeks, leaving a shallow pink depression that may result in scarring. New vesicles appear in
successive crops, resulting in non clustered lesions in all stages of development. These first appear on the
face and scalp, then the trunk, and 2–3 days later on the arms and legs in a centrifugal fashion. Mucous
membranes are also involved, especially the mouth.
