Picture of Gianetti-Crosti Syndrome

Gianotti-Crosti syndrome is a childhood skin condition that caused an itchy, blistering rash. It typically begins on the buttocks and spreads, often to the face and extremities. It's sometimes referred to as papular acrodermatitis of childhood. GCS usually appears while your child is recovering from a viral infection like a respiratory illness or stomach virus. While the blisters can be alarming and the child can have fever and discomfort, there are no lasting effects.
