Eczema is a term used to describe a group of skin conditions that cause irritation, redness, and itching. The appearance of eczema can vary widely depending on the type and severity. Some forms may appear as small bumps, while others may involve large, inflamed patches. The condition is often chronic, with periods of flare-ups and remission. Below, we explore the most common types of eczema, their visual characteristics, and how they differ from one another.
Atopic Dermatitis
Atopic dermatitis is the most prevalent form of eczema, often beginning in childhood. It typically appears as dry, scaly patches on the face, elbows, and knees. In infants, it may present as oozing or crusting lesions. This type is linked to genetic factors and is commonly associated with allergies or asthma.
Contact Dermatitis
Contact dermatitis occurs when the skin reacts to an irritant or allergen. It can be divided into two subtypes: irritant and allergic. Irritant contact dermatitis results from exposure to harsh substances like soaps or chemicals, while allergic contact dermatitis is triggered by allergens like nickel or poison ivy. Symptoms include redness, swelling, and blisters.
Dyshidrotic Eczema
Dyshidrotic eczema primarily affects the hands and feet, causing small, fluid-filled blisters. These blisters can be intensely itchy and may lead to cracked or scaly skin. The exact cause is unknown, but stress and seasonal allergies are common triggers.
Nummular Eczema
Nummular eczema is characterized by coin-shaped patches of irritated skin. These patches can be itchy and may ooze or crust over. This type is more common in older adults and is often triggered by dry skin or environmental factors.
Seborrheic Dermatitis
Seborrheic dermatitis affects oily areas of the body, such as the scalp, face, and chest. It appears as red, scaly patches and is often mistaken for dandruff when it occurs on the scalp. Unlike other forms of eczema, it is not typically itchy.
Stasis Dermatitis
Stasis dermatitis occurs due to poor circulation, often in the lower legs. It presents as swollen, discolored skin and may lead to ulcers in severe cases. This type is more common in individuals with circulatory issues.
