Dyshidrotic eczema or dyshidrosis or pompholyx, is a condition in which the skin, especially the hands and feet, develop small and itchy blisters. Said blisters last up to three weeks and cause intense itching. Cracks and grooves result when the blisters dry, which can be painful.

A physical examination is all that is needed to diagnose dyshidrosis in most cases. However, there are times that a skin biopsy is required to rule out other causes.

Anti-itch medications or antihistamines may be taken to lessen the itching. Moisturizers and strong steroid creams or ointments are also recommended for use. Affected persons are also advised not to scratch the rashes, avoid frequent bathing and using irritating substances since they can worsen the itching.

The condition manifests with small, itchy bumps that develops into a rash made up of blisters or vesicles. Other signs and symptoms include intense itching, cracks or grooves on the fingers and toes, and pain especially if there are large blisters.

There is no known cause for dyshidrosis but it has been observed that it occurs during certain seasons. The condition is also associated with a similar skin disorder called atopic dermatitis and other allergic conditions.
