History: Gianotti-Crosti syndrome, also known as papular acrodermatitis of childhood was first described by Gianotti in 1955.  The onset of the eruption typically occurs in children aged 6 months to 14 years.  Gianotti-Crosti syndrome has been associated with various viral and bacterial infections.  It characteristically presents as an acute, symmetric, exanthematous, asymptomatic or pruritic cutaneous eruption comprised of monomorphous pale, pink-to-flesh–colored or erythematous 1- to 10-mm papules or papulovesicles localized symmetrically and acrally over the extensor surfaces of the extremities, the buttocks, and the face.   It may take 10 days to a few weeks for the eruption to resolve completely.
