Dyshidrotic eczema is a challenging condition to manage due to its chronic and recurrent nature. While the exact cause remains unclear, factors such as metal allergy, occupational exposure, and hyperhidrosis are known to contribute to its development. Effective management often requires a combination of topical treatments and lifestyle modifications to reduce exposure to potential triggers.
Dyshidrotic eczema, also known as dyshidrotic dermatitis or pompholyx, is a chronic skin condition characterized by the appearance of small, pruritic vesicles primarily on the palms, soles, and sides of the fingers. This condition can be particularly distressing due to its recurrent nature and the intense itching it causes.
Clinical Features
Dyshidrotic eczema manifests as small, tense vesicles that are often intensely itchy. These vesicles typically appear on the palmoplantar region and the lateral and ventral surfaces of the fingers. The condition is often associated with hyperhidrosis (excessive sweating) and tends to flare up during the spring allergy season. Histologically, dyshidrotic eczema shows an eczematous reaction around the sweat ducts, although the sweat ducts themselves are not abnormal1.
Etiology
The exact cause of dyshidrotic eczema remains unknown, but several factors are believed to contribute to its development. Metal allergy, particularly to nickel and cobalt, has been identified as a significant etiological factor. Patients with dyshidrotic eczema often show improvement in symptoms when metal allergens are removed from their environment1 4. Other potential triggers include dermatophyte infections, contact irritants, and systemic contact allergens3 4.
Occupational Factors
Occupational exposure to allergens and irritants can also play a role in the development of dyshidrotic eczema. Studies have shown that workers exposed to metalworking fluids and other occupational irritants are at a higher risk of developing this condition. However, the relationship between occupational exposure and dyshidrotic eczema is less frequent compared to other forms of hand eczema3 6.
