dyshidrotic eczema

Dyshidrotic eczema is a fiercely itchy, deep-seated, blistering rash. It is seen most often on the palms of the hands, sides of the fingers, and soles of the feet.

 

Dyshidrotic eczema was once thought to be due to trapping of sweat beneath thick skin of the palms and soles. The cause is unknown; it has been suggested that it may be caused by an inherited allergic response. The skin of the palms, sides of the fingers, and soles of the feet react to something in the environment by forming itchy blisters.

 

Symptoms of dyshidrotic eczema include:

 

Dyshidrotic eczema can affect people of any age but appears to be more common in men between the ages of 20 and 50. There may be a genetic component to the disorder. It has also been suggested that it could be caused by an allergic response to something in the environment. Experts suspect that nickel, balsam, and cobalt may cause the allergic response. Nickel is found in costume jewelry, while the other substances are used in manufacturing.

A person can help prevent dyshidrotic eczema by: allowing feet to air frequently avoiding excessive sweating and excessive dryness avoiding jewelry and other objects made of nickel avoiding unnecessary exposure to soapy water bathing with mild soap and lukewarm water and rinsing soap off well following measures to prevent athlete's foot taking good care of his or her skin using heavy-duty gloves to protect the hands against chemicals wearing cotton socks

Diagnosis of dyshidrotic eczema begins with a medical history and physical exam. The healthcare professional may order blood tests to check for other causes of the rash.
