There are many different types of eczema, and the symptoms can vary from person to person. Atopic dermatitis, the most common form of eczema, typically causes dry, itchy skin. Contact dermatitis occurs when the skin comes into contact with an irritant, such as a detergent or poison ivy.
This can cause a red, itchy rash. Dyshidrotic eczema causes small, itchy blisters on the palms of the hands and soles of the feet. Nummular eczema causes coin-shaped patches of itchy, scaly skin. Seborrheic dermatitis, another common form of eczema, causes a red, itchy rash with oily, scaly patches.
