There are five basic types of dermatitis:
- Atopic dermatitis (AD). Characterized by itching, scaling, and
swelling rash on the skin that may form oozing open sores or
yellow and red pimples, the rash is most likely to affect the skin
of the hands and feet, the arms, the area behind the knees, and the
ankles, wrists, face, neck, and upper chest. - Contact dermatitis. Rashes caused by touching a foreign substance.
There are two major forms of contact dermatitis: allergic,
caused by contact with a plant or animal substance that a person
has become sensitized to; and irritant, caused by touching something
that damages the skin directly. Poison ivy is an example of
an allergic contact dermatitis; rashes caused by detergents or
other household chemicals are examples of irritant contact
dermatitis. - Cercarial dermatitis. Commonly known as swimmer’s itch, it is
caused by certain parasites that live in ducks, geese, and freshwater
snails. (A parasite is an organism that lives off another, larger,
organism.) When a person swims in water containing these parasites,
they can burrow into the skin and cause a short-lived itchy rash with
small reddish pimples or blisters. It mostly affects the parts of the-
body that are not covered by a swimsuit, and does not usually affect
the face, palms of the hands, or soles of the feet. - Radiation dermatitis. The most common form of radiation dermatitis
is photodermatitis or sunburn. It is characterized by redness, pain,
and swelling of the affected skin following exposure to sunlight or a
tanning lamp. Severe sunburn includes the formation of blisters and
peeling of the affected skin, which usually begins to peel about three
days after exposure and may continue for another week or so. A
rarer form of radiation dermatitis, found mostly among hospital staff,
is caused by repeated exposure to x-ray and other imaging
equipment in hospitals. - Seborrheic dermatitis. Found on the scalp and other areas of the face
and chest that contain oil-secreting glands, it is characterized
by a reddish, greasy-looking rash on the skin and oily flakes of skin.
In infants, it is called cradle cap. In adults, the most common form of
seborrheic dermatitis isdandruff.
