Causes of Acrodermatitis
The cause of acrodermatitis is poorly understood, but its link with other infections is well-documented.
In Italian children, acrodermatitis 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 cytomegalovirus, coxsackie viruses, parainfluenza virus, respiratory syncytial virus (RSV), and some live virus vaccines.
A rare, genetic form of acrodermatitis is acrodermatitis enteropathica. In this disorder, zinc is poorly absorbed from the diet. Adding zinc supplements to the diet improves the condition. This form of the disorder can be associated with other abnormalities and development delays.
- Rash or patch on skin
- Brownish-red or copper-colored patch that is firm and flat on top
- String of bumps may appear in a line
- Generally not itchy
- Rash looks the same on both sides of the body
- Rash may appear on the palms and soles -- it does not occur on the back, chest, or belly area (this is one of the ways it is identified -- by the absence of the rash from the trunk of the body)
Other symptoms that may appear include:
Tests and Exams
Your doctor 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:
- Bilirubin level
- Hepatitis virus serology or hepatitis B surface antigen
- Liver enzymes (liver function tests)
- Screening for EBV antibodies
- Serum zinc level may be tested in acrodermatitis enteropathica
- Skin biopsy
Treatment of Acrodermatitis
Acrodermatitis by itself is not treated. Infections associated with this condition, such as hepatitis B and Epstein-Barr, are treated. Cortisone creams may help with itching and irritation.
Acrodermatitis enteropathica improves when the zinc levels in the body is returned to normal.
Acrodermatitis usually disappears on its own without treatment or complication. Associated conditions must be watched carefully.
Complications occur as a result of associated conditions, rather than as a result of acrodermatitis.
