Overview
Dermatitis
Dermatitis is an umbrella term used to describe various skin irritations and rashes resulting from genetics, an overactive immune system, infections, allergies, and contact with irritating substances. Common symptoms include dry skin, redness, and itchiness. The term “dermatitis” combines “derm” (skin) and “itis” (inflammation), thus literally translating to “inflammation of the skin.” Dermatitis ranges from mild to severe and can cause significant discomfort but does not pose serious harm to the body. It is not contagious and does not indicate uncleanliness or infection of the skin.
Types of Dermatitis
Dermatitis can be classified by its cause, clinical appearance, or the site of predilection. Some of the main types include:
Atopic Dermatitis (Eczema): Common in children and adults, often associated with asthma and hay fever.
Contact Dermatitis: Triggered by contact with allergens or irritants.
Seborrheic Dermatitis: A chronic form affecting areas like the face, scalp, and ears, often due to a reaction to yeasts on the skin.
Dyshidrotic Dermatitis: Characterized by itchy blisters on the edges of fingers, palms, toes, and soles.
Nummular Dermatitis: Presents as circular, itchy spots on the skin.
Stasis Dermatitis: Results from poor blood flow in the veins, often affecting the ankles.
