DefinitionDyshidrotic eczema is a condition in which small blisters that cause intense itching develop on the hands and feet.
Causes, incidence, and risk factorsThe cause of dyshidrotic eczema is not known, but it occasionally appears to be seasonal. Small fluid filled blisters called vesicles appear on the hands and feet. They are most common along the edges of the fingers, toes, palms and soles. The vesicles produce intense itching. Scratching leads to skin changes with thickening. Scratching may also lead to secondary infections .
Signs and tests
Your physician may often diagnose dyshidrotic eczema based upon the appearance of your skin. Occasionally, a skin biopsy or skin scraping may be needed to rule out other causes.
Expectations (prognosis)Dyshidrotic eczema normally resolves without problems. Uninhibited scratching and skin trauma may lead to thick, irritated skin which is more difficult to treat and has a longer healing time.
Calling your health care providerSigns or symptoms of infection are present (tenderness, redness, warmth, or fever), or your rash does not clear with simple home therapy.
