Overview
Dyshidrosis, also known as dyshidrotic eczema or pompholyx, is a chronic skin condition characterized by small, fluid-filled blisters that appear on the palms of the hands, sides of the fingers, and sometimes on the soles of the feet. These itchy blisters tend to recur and can significantly impact a person’s quality of life.
Types of Dyshidrosis
- Vesicular Dyshidrosis: The most common type, characterized by clusters of tiny blisters resembling tapioca pearls.
- Pompholyx: Another term for dyshidrosis, specifically referring to the blisters on the hands and feet.
Causes of Dyshidrosis
The exact cause of dyshidrosis remains unknown, but several factors may contribute:
- Atopic Dermatitis (Eczema): Individuals with a history of atopic dermatitis are more prone to dyshidrosis.
- Allergic Conditions: Hay fever or glove allergy may play a role.
- Stress: Emotional or physical stress can trigger flare-ups.
- Exposure to Certain Metals: Cobalt and nickel exposure (commonly in industrial settings) may contribute.
- Sensitive Skin: Those who develop rashes after contact with irritants are at higher risk.
Risk Factors of Dyshidrosis
Certainly! Here are the risk factors associated with dyshidrosis:
- Stress: Dyshidrosis tends to be more common during times of emotional or physical stress.
- Exposure to Certain Metals: Cobalt and nickel exposure, often in industrial settings, can trigger dyshidrosis.
- Sensitive Skin: Individuals who develop rashes after contact with irritants are more likely to experience dyshidrotic blisters.
- Atopic Dermatitis (Eczema): People with a history of atopic dermatitis may be at higher risk for dyshidrosis.
Symptoms of Dyshidrosis
1. Painful, itchy blisters on the fingers, palms, and soles.
2. Blisters are small, about the width of a pencil lead, often grouped in clusters.
3. Skin affected by dyshidrosis can be painful and very itchy.
4. After a few weeks, blisters dry up and flake off.
Preventions of Dyshidrosis
While prevention isn’t always possible, consider the following:
- Stress Management: Reduce stress to minimize flare-ups.
- Avoid Metal Exposure: Be cautious around cobalt and nickel.
- Good Skin Care Practices: Use mild cleansers, moisturize, and protect your hands with gloves.
Diagnosis of Dyshidrosis
- No specific lab test for diagnosis.
- Physical examination by a dermatologist helps confirm the condition.
Treatment for Dyshidrosis

- Newer options like dupilumab (a biologic medication) may be considered.
