Definition of Acrodermatitis

Acrodermatitis is a childhood skin condition that may be accompanied by mild symptoms of and malaise. It may also be associated with hepatitis B and other viral infections.

Causes, incidence, and risk factors

The cause of acrodermatitis is poorly understood, but its link with other infections is well- documented.

Signs and tests

Your doctor can diagnosed this condition by simply looking at the skin and rash. The liver, spleen, and lymph nodes may be swollen.


Acrodermatitis by itself is not treated. Infections associated with this condition, such as hepatitis B and Epstein-Barr, should be treated appropriately.

Expectations (prognosis)

Acrodermatitis usually disappears on its own without treatment or complication. However, the associated conditions must be watched carefully.
