Dyshidrotic Eczema (Dyshidrosis)

What is dyshidrotic eczema?

Dyshidrotic eczema, also known as pompholyx, is a distinct skin condition marked by small, fluid-filled blisters or vesicles. These blisters typically appear on the fingers, palms, toes, and the soles of the feet. The exact cause of dyshidrotic eczema is not well-defined, but various factors might play a role in its development. Although the condition can be distressing, it's often self-limiting, with most cases resolving in about 3 weeks.

While the root cause of dyshidrotic eczema remains elusive, several factors are believed to potentially contribute to its onset, including:

• Exposure to allergens

• Frequent hand washing or prolonged contact with water

• Emotional or physical stress

• Sensitivity to specific metals like nickel or cobalt

• Seasonal changes, particularly during spring and summer

What are the symptoms of dyshidrotic eczema?

Individuals with dyshidrotic eczema might experience:

• Persistent itchiness on the palms and soles

• Formation of small blisters or vesicles, primarily on the fingers, toes, palms, and soles

• Symmetrical distribution of these blisters, though they generally do not spread to other parts of the body

How do I treat dyshidrotic eczema?

While comprehensive research on treatment for dyshidrotic eczema is still in progress, several medical therapies have been found to alleviate symptoms. These may include:

• Topical corticosteroids to reduce inflammation

• Barrier creams or moisturizers to protect the skin and lock in moisture

• Antihistamines to manage itching

• Soaking in a dilute solution of potassium permanganate to dry out blisters
