Gianotti-Crosti syndrome after H1N1-influenza vaccine.

Papular acrodermatitis of childhood, or Gianotti-Crosti syndrome, is a symmetric papular or papulovesicular acral exanthem associated with several infectious agents and immunizations. We present a case of Gianotti-Crosti syndrome appearing shortly after H1N1-influenza vaccination. This has not been previously reported to our knowledge.
