Eczema generally appears as a dry, thickened or scaly rash, according to WebMD, which also offers photographs. Affected areas may present as a reddish color and then turn brown in fair-skinned people, while darker-skinned people may experience a change in pigmentation causing the area to appear lighter or darker.
Infants affected by eczema may experience an oozing, crusting rash that commonly presents on the face and scalp, but patches may appear anywhere. Infants are relatively commonly affected by eczema, writes WebMD, with 10 to 20 percent of infants experiencing the condition, while about 3 percent of adults and children in the United States have eczema.
In addition to the presentation of a rash, eczema is almost always itchy, states WebMD. While it may affect other areas of the body, it often appears on the face, back of the knees, wrists, hands or feet.
