Un guide sur la dermatite couvrant les signes et symptômes, la prévention et le traitement.

Dermatitis (also known as eczema) is inflammation of the skin, typically characterized by itchiness, redness and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. The area of skin involved can vary from small to covering the entire body.

Dermatitis includes atopic dermatitis, allergic contact dermatitis, irritant contact dermatitis, seborrhoeic dermatitis and stasis dermatitis. The exact cause of the condition is often unclear.Cases may involve a combination of allergy and poor venous return.The type of dermatitis is generally determined by the person's history and the location of the rash. For example, irritant dermatitis often occurs on the hands of those who frequently get them wet. Allergic contact dermatitis occurs upon exposure to an allergen, causing a hypersensitivity reaction in the skin.
