Atopic dermatitis (AD), also known as eczema, is a chronic inflammatory skin condition that causes dry, intensely itchy skin and can significantly impact quality if life. While it presents differently from person to person, dermatologists often classify it into several types or patterns based on age, appearance, triggers, and severity.
Below are the commonly recognized types and subtypes:
Main Types of Atopic Dermatitis
1. Infantile Atopic Dermatitis (0–2 years)
- Usually starts on the cheeks, scalp, and extensor surfaces (arms and legs).
- Skin appears red, weepy, oozing, and very itchy.
- Often triggered by drooling, scratching, or food sensitivities.
2. Childhood Atopic Dermatitis (2–12 years)
- Commonly affects flexural areas (elbows, knees, neck, wrists, ankles).
- Skin becomes dry, thickened (lichenified) from chronic scratching.
- Flare-ups may be triggered by environmental allergens, sweating, or stress.
3. Adult Atopic Dermatitis (12+ years)
- Can persist from childhood or appear for the first time.
- Often shows dry, scaly patches, especially on the hands, face, neck, and upper body.
- Adults may have more lichenification, chronic itching, and risk of secondary infection.
Specific Clinical Subtypes of Atopic Dermatitis
4. Acute, Subacute, and Chronic AD
- Acute: Red, swollen, blistering or oozing skin.
- Subacute: Dry, scaly, red patches.
- Chronic: Thickened, leathery skin from prolonged scratching.
5. Flexural Dermatitis
- Involves skin folds: elbows, knees, neck.
- Common in older children and adults.
6. Nummular (Discoid) Eczema
- Round or coin-shaped plaques.
- Very itchy, often confused with fungal infection.
7. Dyshidrotic Eczema (Pompholyx)
- Small, itchy blisters on palms, fingers, or soles.
- Often triggered by stress, sweating, or allergies.
8. Prurigo Nodularis–Type AD
- Characterized by hard, itchy nodules from chronic scratching.
- Usually seen in adults with long-standing AD.
9. Follicular Eczema
- Instead of patches, tiny bumps appear around hair follicles.
-
More common in people with darker skin types.
10. Erythrodermic Atopic Dermatitis (Rare, Severe)
- Involves widespread redness and scaling over most of the body.
- A dermatologic emergency; risk of dehydration, infection, and temperature dysregulation.
Other Related Patterns
These may coexist with AD:
11. Head-and-Neck Dermatitis
Often seen in adults; associated with Malassezia yeast sensitivity.
12. Hand Dermatitis
Common in people with frequent handwashing or irritant exposure (healthcare, cleaning jobs).
How is it managed?
Symptoms can come and go, and while it can’t be cured, it can be managed effectively to reduce symptoms and prevent flare-ups.
Constantly moisturize the skin to keep it well-hydrated with fragrance-free creams or ointments is crucial to relieve discomfort and reduce flare up. Be able to identify and avoid triggers. This can include certain foods, irritants, and environmental factors like molds. Daily bathing with soap free cleansers like Hydro Rain containing PDRN for skin barrier protection and repair followed by liberal use of emollients or cream like Skin Atoz which is all natural ingredient is a key part of daily maintenance.
It is best to work with a dermatologist or a healthcare provider that can help find a personalized management plan.
