dermatitis

The dermatitis - Inflammation of the skin, sometimes due to an allergy. Dermatitis is the same as eczema, and the terms can be used interchangeably. The following are types of dermatitis.

SEBORRHOEIC DERMATITIS
This condition is a red, scaly, itchy rash that develops on the face (particularly the nose and eyebrows), scalp, chest, and back. It often develops during times of stress and is probably caused by an excessive growth of yeast on the skin. Corticosteroid drugs and drugs that kill microorganisms may help.

An allergic reaction to the metal (often nickel)

in a ring has produced a red, inflamed area of

skin around the finger.

CONTACT DERMATITIS
Contact dermatitis results from a reaction to some substance that comes in contact with the skin. Common causes are detergents, nickel, certain plants, and cosmetics. It may be treated with topical corticosteroids. A patch test (see skin tests) may be performed in order to identify the cause.

PHOTODERMATITIS:
This form of dermatitis occurs in people whose skin is abnormally sensitive to light. A cluster of spots or blisters occurs on any part of the body exposed to the sun (see photosensitivity).
