Almost always, there's an itch before a rash appears in eczema. Typically, eczema shows itself as:
Patches of chronically itchy, dry, thickened skin, usually on the hands, neck, face, and legs. In children, the inner creases of the knees and elbows are often involved.
Scratching can lead to sores with crusts.
Dry skin is defined as flaking or scaling -- which may or may not be itchy -- when there is no evidence of dermatitis, or inflammation, of the skin. Some flaking along with redness, however, may be a sign of an underlying dermatitis. There are different types of dermatitis that may cause dry, itchy, flaking skin.
