Dyshidrotic eczema, or pompholyx, is a common but incurable skin condition characterized by small, itchy blisters, often appearing in spring. It affects around 35 million Americans, with 70% being children under five. Eczema refers to a group of skin inflammation diseases causing red, itchy, swollen skin, sometimes with fluid-filled bumps that ooze or crust. Triggers include allergies and genetics, but eczema is not contagious. Dyshidrotic eczema specifically affects the hands (cheiropompholyx), feet (podopompholyx), or both (cheiropodopompholyx).
