About Dyshidrotic Eczema
Dyshidrotic eczema, also known as dyshidrosis or pompholyx, is a skin condition characterized by the development of blisters on the soles of the feet or the palms of the hands and fingers. It is a type of eczema that involves flare-ups lasting several weeks.
The exact cause of dyshidrotic eczema is not known, but it may be triggered by factors such as allergies, genetics, or stress. The blisters associated with dyshidrotic eczema are usually very itchy and may contain fluid. They can appear as tiny bumps on the fingers or grow together to cover larger areas on the hands and feet. Other symptoms may include redness, flaking, scaly or cracked skin, and pain near the blisters.
While there is currently no cure for dyshidrotic eczema, treatments aim to reduce symptoms and prevent complications. These may include moisturizers, anti-itch medications, prescription corticosteroids, cold compresses, stress management, and removing jewelry before hand washing. If symptoms persist for more than a week, it is advisable to consult a healthcare professional for further evaluation and guidance.
The exact pathophysiologic causes of dyshidrotic eczema are not fully understood. However, there are several factors that may contribute to the development of this condition:
Non-modifiable risk factors cannot be controlled or changed. They include:
- Age: Dyshidrotic eczema is more common in people under 40 years of age.
- Gender: It is more common in females.
- Family history: Having a family history of dyshidrotic eczema can make you more susceptible.
- Other types of eczema: Having another form of eczema increases the risk of developing dyshidrotic eczema.
Modifiable risk factors can be influenced by individual habits and lifestyle. They include:
- Allergies and sensitivities: Having seasonal allergies or asthma, an allergy to certain metals (such as nickel), or hypersensitivity to certain foods, chemicals, or substances can increase the risk.
- Sweating and wetness: Having hands or feet that frequently sweat or become wet can be a contributing factor.
- Occupational exposure: Working with metals, being a mechanic, or working with cement may increase the risk.
It's important to note that while these factors may increase the likelihood of developing dyshidrotic eczema, they do not guarantee its development. If you have concerns about your risk factors or symptoms, it is best to consult with a healthcare professional for an accurate diagnosis and appropriate management plan.
Common symptoms of dyshidrotic eczema include:
- Burning and itching sensation without any visual clues
- Sudden appearance of tiny, itchy blisters on the palms, sides of fingers, and feet
- Blisters can grow together and form larger areas that are red, itchy, and raised
As dyshidrotic eczema progresses or becomes more severe, the following symptoms may occur:
- Skin becoming dry and peeling as the blisters heal
- Dark spots on the skin where the blisters have healed (more common in individuals with dark skin tone)
- Painful blisters that ooze pus if the skin becomes infected
- Swollen, tender skin
- Flushed, itchy skin
- Scaly, cracked, or flaking skin
- Painful skin patches
- Painful skin fissures (cracks in the skin)
It's important to note that symptoms can vary from person to person. If you're experiencing any of these symptoms, it's best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
To diagnose dyshidrotic eczema, the following examinations, tests, and procedures may be performed:
- Medical history: The doctor will ask about your symptoms, when they started, and if you have any other types of eczema. They may also inquire about any family members with dyshidrotic eczema.
- Physical examination: A dermatologist will closely examine the affected skin on your hands or feet.
- Allergy testing: Your doctor may recommend allergy testing to identify specific triggers that could be aggravating your eczema.
- Skin patch testing: In some cases, a patch test may be conducted to determine if a particular allergy is causing your dyshidrotic eczema.
To determine the severity of dyshidrotic eczema, additional examinations, tests, and procedures may include:
- Skin biopsy: In certain cases, a skin biopsy may be performed to examine a small sample of skin under a microscope for further evaluation.
- Further testing: If your symptoms do not improve after 24 weeks of treatment, your doctor may consider additional testing to rule out other conditions such as bacterial, fungal, or viral infections.
Remember, it is essential to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan.
The goals of treatment for dyshidrotic eczema are to manage symptoms, relieve pain, prevent flare-ups, and improve the overall quality of life. Treatment options and how they work to achieve these goals include:
Medications:
- Corticosteroid creams: These topical medications reduce inflammation, ease irritation, and promote healing.
- Anti-itch medications: Antihistamine pills or lotions can reduce itching and discomfort.

- Acupuncture and acupressure: These techniques may provide relief from symptoms
- Wet soaking with potassium permanganate: Helps with oozing blisters
- Botox injections: Lessen sweating and excess moisture in the hands and feet, which can prevent infections
