Eczema is a general term for any type of dermatitis or “itchy rash”. There are several skin diseases that are eczemas. All types of eczema cause itching and redness and some will blister, weep or peel. It typically affects the insides of the elbows, backs of the knees, and the face, but some eczema types can cover most of the body.
