Eczema, clinically termed atopic dermatitis, is a widespread chronic skin condition marked by irritating dryness and itching. Although people of all ages may be affected by it, children are at the greatest risk, and it can have a major effect on quality of life.
Hence, learning about the different causes, symptoms and ways to control the disease is essential for successful management.

What are the Types of Atopic Dermatitis?
Atopic dermatitis, the most common form of eczema, can present in various forms. Here are some types and variations:
Type
Age of Onset
Common Locations
Key Features
Prevalence
Infantile Atopic Dermatitis
2–6 months
Face, scalp, extensor surfaces
Red, weeping, crusted lesions
It often improves with age and may persist or evolve into other forms.
Childhood Atopic Dermatitis
2–12 years
Flexural areas (elbows, knees)
Dry, scaly, itchy patches
May continue into adolescence or adulthood.
Adult-Onset Atopic Dermatitis
After 18 years
Hands, eyelids, and flexural areas
Lichenified plaques, chronic itching
Usually persistent, with periods of relief and intensification
Intrinsic (Non-Allergic) Atopic Dermatitis
Variable
Similar to other forms
Normal IgE levels, no allergen-specific IgE
Accounts for 20% of cases; not associated with allergies.
Represents 80% of cases; associated with other atopic conditions like asthma and allergic rhinitis.
Nummular (Discoid) Dermatitis
Variable
Extremities, especially legs
Coin-shaped, well-demarcated plaques; itchy and may ooze
It can be chronic and recurrent.
Prurigo Nodularis
Variable
Extensor surfaces of limbs
Firm, dome-shaped nodules; intense itching
Linked with severe, persistent itch; results from chronic scratching.
Erythrodermic Atopic Dermatitis
Variable
Widespread (most of the body surface)
Extensive redness, scaling, and exfoliation
Severe and potentially life-threatening; requires immediate medical attention.
Lichenoid Dermatitis
Variable
Wrists, forearms, lower legs
Flat-topped, violaceous papules with fine scales
Associated with chronic AD; requires targeted therapy.
Follicular Atopic Dermatitis
Variable
Upper arms, thighs, cheeks
Small, rough papules centered around hair follicles; sandpaper-like texture
More common in individuals with darker skin tones.
What are the Causes of Eczema?
The exact cause of eczema is multifactorial, involving a combination of genetic and environmental factors:
Genetic Predisposition: Any mutation in the filaggrin (FLG) gene, which strengthens the skin barrier, can make a person more likely to develop atopy.
Immune System Dysfunction: Immune system hyperreactivity leads to inflammation in response to certain stimuli.
Environmental Triggers: Exposure to things that cause allergies (such as pollen or dust), irritants (such as soaps or detergents), or low humidity can worsen the symptoms.
Stress: Emotional stress can worsen or trigger flare-ups.
Skin Barrier Defects: If skin proteins are altered by mutations, the skin’s ability to protect against drying is reduced and becomes susceptible to irritating factors.
What are the Symptoms of Eczema?
Eczema symptoms can vary but commonly include:
Dry, Sensitive Skin: The skin might feel rough and look flaky.
Itching: Often causes severe itching, which further damages the skin.
Red or Inflamed Patches: Most noticeably on the face, neck and limbs.
Thickened, Cracked, or Scaly Skin: Due to continuous scratching.
Oozing or Crusting: In the event of infection.
Hyperpigmentation or Hypopigmentation: The skin may turn discolored after inflammation.
What is the Diagnosis of Eczema?
Diagnosis is primarily clinical, based on:
History of Symptoms: Onset, duration, and pattern.
Family Medical History: In the context of atopic conditions.
Physical Examination: Evaluating the pattern and appearance of the skin lesion.
Allergy Testing: To identify specific triggers.
Skin Biopsy: To eliminate secondary causes.
What are the Treatment Options for Eczema?
While there is currently no cure, eczema treatment aims to manage symptoms and prevent flare-ups:
1. Topical Therapies:
Emollients: Use a moisturizer daily to keep the skin well hydrated.
Corticosteroids: To lower inflammation during a flare-up.
Calcineurin Inhibitors: For sensitive areas or intended for long-term use.
2. Systemic Treatments:
Antihistamines: To relieve the sensation of itching.
Immunosuppressants: If topical treatments do not respond in extreme cases.
Biologic Therapies: Such as dupilumab, are designed to treat moderate-to-severe eczema.
3. Phototherapy:
Supervised exposure to ultraviolet light.
Consulting with a healthcare provider helps you choose the most effective plan for treatment.
What are the Complications of Eczema?
Eczema can lead to further issues if not effectively controlled. They are as follows:
Skin Infections: Open wounds created by scratching can be invaded by bacteria (for example, Staphylococcus aureus), viruses (for example, herpes simplex, resulting in eczema herpeticum) or fungi, sometimes resulting in cellulitis or sepsis.
Chronic Skin Changes: Chronic scratching can lead to the development of thick, leathery patches that won’t disappear.
Sleep Disturbances: Constant itching late at night may prevent people from sleeping well, leaving them feeling much worse during the day.
Mental Health Issues: The chronic nature of eczema and its obvious signs can lead to stress and conditions such as anxiety and depression.
Eye Complications: Severe eczema around the eye can result in conjunctivitis, keratitis or cataracts.
How to Care and Manage Individuals With Eczema?
Effective eczema management involves:
Identifying and Avoiding Triggers: Such as allergens, irritants, and stressors.
Maintaining Skin Hydration: Through regular use of emollients.
Implementing a Skincare Routine: Using gentle, fragrance-free products.
Wearing Soft, Breathable Fabrics: To minimize skin irritation.
Regular Monitoring: Follow-ups with healthcare providers are needed to adjust treatment as needed.
Stress Management: Incorporating relaxation techniques into daily routines.
Dietary Considerations: Identifying and avoiding food triggers, if applicable.
