Dermatitis

Dermatitis is "inflammation" of the skin. The etiology of dermatitis may be idiopathic or secondary to known irritants or allergens.

Types of Eczema (Dermatitis)

Allergic contact eczema (dermatitis): a red, itchy, weepy reaction where the skin has come into contact with a substance that the immune system recognizes as foreign, such as poison ivy or certain preservatives in creams and lotions

Atopic dermatitis: a chronic skin disease characterized by itchy, inflamed skin

Contact eczema: a localized reaction that includes redness, itching, and burning where the skin has come into contact with an allergen (an allergy-causing substance) or with an irritant such as an acid, a cleaning agent, or other chemical

Dyshidrotic eczema: irritation of the skin on the palms of hands and soles of the feet characterized by clear, deep blisters that itch and burn

Neurodermatitis: scaly patches of the skin on the head, lower legs, wrists, or forearms caused by a localized itch (such as an insect bite) that become intensely irritated when scratched

Nummular eczema: coin-shaped patches of irritated skin-most common on the arms, back, buttocks, and lower legs-that may be crusted, scaling, and extremely itchy

Seborrheic eczema: yellowish, oily, scaly patches of skin on the scalp, face, and occasionally other parts of the body

Stasis dermatitis: a skin irritation on the lower legs, generally related to circulatory problems
