Dyshidrotic Eczema
Alternate Names : Dyshidrosis, Pompholyx
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.
What is going on in the body?
Dyshidrotic eczema was once thought to be due to trapping of sweat beneath
thick skin of the palms and soles. Most healthcare providers now believe that
it is 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.
What are the causes and risks of the condition?
Dyshidrotic eczema can affect people of any age but appears to be
more common in men between the ages of 20 and 50. There seems to be a genetic
component to the disorder. It is probably 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. Risk factors that increase a person's risk
for dyshidrotic eczema include:
anxiety
bacterial infection
certain skin infections
difficulty expressing feelings or emotions
hot or cold temperatures
increased humidity
personal or family history of
asthma,
sinusitis, or hay
fever
recent immunoglobulin therapy
seasonal changes
stress
Some experts believe that a fungal infection elsewhere in the body
can cause dyshidrotic eczema on the hands. For example, someone with athlete's foot may develop eczema
lesions on his or her hands.
The following factors have been linked to dyshidrotic eczema, but
more research is needed to be sure:
aspirin
cigarette smoking
metal implants, such as total hip
replacements
oral contraceptives
