Answer

Scabies manifests in infancy or childhood as a pruritic eruption. Other members of the family are usually itchy, and the primary sites of involvement are moist, warm areas. The eruption is polymorphic with a dermatitis, nodules, urticaria, and 6-10 burrows. Pustules on the hands and feet are almost diagnostic of scabies in infancy. Facial involvement is rare, and xerosis does not occur.
