I Would Like to Learn About:

Causes

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:

Symptoms

Skin symptoms may include any of the following:

Other symptoms that may appear include:

Exams and Tests

The provider can diagnose this condition by looking at the skin and rash. The liver, spleen, and lymph nodes may be swollen.

The following tests may be done to confirm the diagnosis or rule out other conditions:

Treatment

The disorder itself is not treated. Infections linked with this condition, such as hepatitis B and Epstein-Barr, are treated. Cortisone creams and oral antihistamines may help with itching and irritation.

Outlook (Prognosis)

The rash usually disappears on its own in about 3 to 8 weeks without treatment or complication. Associated conditions must be watched carefully.

Possible Complications

Complications occur as a result of associated conditions, rather than as a result of the rash.

When to Contact a Medical Professional

Call your provider if your child has signs of this condition.
