Xerotic Eczema

Xerotic eczema, in the simplest terms, also known as asteatotic eczema or winter itch, is a skin condition that results in extremely dry, itchy skin. It’s also known as ‘winter itch’ because it often gets worse in dry, cold weather conditions. The name ‘xerotic’ comes from ‘xerosis’, which means dryness. Eczema, on the other hand, is a broad term for conditions that cause the skin to become inflamed, red, itchy, and cracked. Anyone can get xerotic eczema, but it’s more common in older adults. This is because our skin tends to become drier as we age, and dry skin is more prone to this condition. It’s not contagious, which means it can’t be passed from person to person. The main cause of xerotic eczema is dry skin. This can happen due to various factors, like cold, dry weather, not drinking enough water, or using harsh soaps and detergents that strip natural oils from your skin.

Xerotic Eczema is a type of skin condition that occurs when the skin becomes excessively dry. It is most common during winter months when the air is dry and cold, causing the skin to lose moisture. This condition affects people of all ages and, if not treated, can lead to painful cracks in the skin.

Types of Xerotic Eczema

Xerotic Eczema can present in different forms. Let’s dive into the most common types.

1. Classic Xerotic Eczema

Classic Xerotic Eczema is the most common type. It usually appears as areas of dry, itchy skin. When you touch it, it might feel rough, like sandpaper. The itching can get worse at night, causing trouble sleeping. It mainly shows up on arms and legs but can also affect other parts of the body.

2. Prurigo nodularis

This form of Xerotic Eczema can cause hard, itchy lumps to appear on the skin. The constant itch and the urge to scratch can cause these lumps to become even harder and sometimes, they might even bleed.

3. Asteatotic Eczema

Asteatotic Eczema is another type of Xerotic Eczema that primarily affects older adults. The skin becomes so dry it cracks, resembling a parched river bed. This cracking can be painful and lead to infections if not properly cared for.

4. Nummular Eczema

Nummular Eczema is characterized by round or oval-shaped itchy patches that can appear anywhere on the body. The patches can be pink, red, or brown and may ooze or become scaly.

Causes

Causes of a skin condition called Xerotic Eczema, also known as “dry skin eczema”. Let’s dive into it, making sure to use straightforward, easy-to-understand language.

1. Low Humidity: Living in areas with low moisture in the air can rob your skin of its natural moisture, leading to xerotic eczema. Consider investing in a humidifier if you live in dry climates.

14. Reduced Flexibility: Skin loses its flexibility, becoming less stretchy and more prone to cracking.
15. Increased Sensitivity: Skin becomes more sensitive to touch and may react to substances it was previously fine with.
16. Exacerbation in Cold Weather: Symptoms can get worse in cold, dry weather, much like how certain conditions become more painful in the cold.
17. Eczema ‘Rash’: The dry, rough skin can appear like an overall rash.
18. Increased Thickness: Affected skin may become thicker from persistent itching and scratching.
19. Bacterial Infections: If skin cracks and bleeds, bacteria can enter, leading to infection. Symptoms of this might include warmth, pus, or increased redness.
20. Psychological Distress: Dealing with persistent itchiness and discomfort can lead to feelings of stress or anxiety.

Diagnosis

Diagnoses and tests for Xerotic Eczema.

1. Clinical Examination: The primary step in diagnosing Xerotic Eczema involves a physical examination. Doctors look for signs like dry, scaly, or cracked skin to confirm the condition.
2. Medical History Evaluation: The doctor will consider your past medical conditions, allergies, family history of skin conditions, and lifestyle factors like exposure to irritants.
3. Skin Patch Testing: This test involves applying small patches covered with potential irritants to your skin. It helps identify allergens that may be causing or worsening your eczema.
4. Skin Prick Test: By pricking the skin lightly with a tiny amount of an allergen, doctors can observe if your skin reacts. This test helps diagnose related allergies.
5. KOH Test: A small sample of your skin cells may be taken and examined under a microscope using potassium hydroxide. This test rules out fungal infections.
6. IgE Blood Test: This test measures the level of Immunoglobulin E, an antibody that increases in response to an allergen. High levels may point towards allergic eczema.
7. Eosinophil Count: An increase in these white blood cells may indicate an ongoing allergic response, commonly found in people with eczema.
8. Skin Biopsy: Although rare for Xerotic Eczema, a skin biopsy can rule out other skin diseases that mimic eczema, like psoriasis or dermatitis herpetiformis.
9. Dermatoscopy: Using a dermatoscope, doctors can observe the skin more closely. It helps assess the severity and nature of the skin’s dryness and cracking.
10. Infrared Thermography: This method measures skin temperature, aiding in understanding inflammation levels associated with eczema.
11. Transepidermal Water Loss Measurement: This test assesses the skin’s barrier function. Increased water loss may indicate severe dryness, a common feature of Xerotic Eczema.
12. Skin Hydration Measurement: Using devices like a corneometer, this test measures skin’s water content, further helping in evaluating skin dryness.
13. Fungal Culture: If doctors suspect a fungal infection exacerbating your eczema, they might conduct this test.
14. Bacterial Culture: Similar to a fungal culture, a bacterial culture is done if there’s suspicion of a bacterial infection on top of your eczema.
15. Skin pH Measurement: Eczematous skin often has a higher pH. Measuring skin pH can provide additional information about the skin condition.
