Gianotti-Crosti syndrome is a skin rash especially in children, triggered by a viral, or more seldom by a bacterial infection. Reddish papules are seen on the skin in clusters or coalesced to form elevated patches. In the extremities the rash is located especially at the elbows and knees but only on the extensor sides. The skin is intact. There is no significant itching. The rash will resolve spontaneously in a few weeks. See also a picture of symmetrical rash on the cheek.
