Gianotti-Crosti syndrome is a childhood skin condition that may be accompanied by mild symptoms of fever and malaise. It may also be associated with hepatitis B and other viral infections.
Health care providers don't know the exact cause of this disorder. They do know that it is linked with other infections.
In Italian children, Gianotti-Crosti syndrome is seen frequently with hepatitis B. But this link is rarely seen in the United States. Epstein-Barr virus (EBV, mononucleosis) is the virus most often associated with acrodermatitis.
Other associated viruses include:
Skin symptoms may include any of the following:
Other symptoms that may appear include:
The provider can diagnose this condition by looking at the skin and rash. The liver, spleen, and lymph nodes may be swollen.

Complications occur as a result of associated conditions, rather than as a result of the rash.
Call your provider if your child has signs of this condition.
