Understanding Discoid Eczema: A Comprehensive Overview

Discoid eczema, also known as nummular or discoid dermatitis, is a chronic skin condition characterized by distinct circular or oval patches of inflamed skin. This condition can affect any part of the body, although it rarely appears on the face or scalp. To better understand this skin disorder, let’s delve into its key aspects, symptoms, causes, and treatment options.

Recognizing the Symptoms of Discoid Eczema

Discoid eczema manifests through several distinctive symptoms:

Circular or oval patches of eczema
Itchy, reddened, and swollen skin
Small red spots or bumps that coalesce into larger patches
Blistering and fluid oozing in the early stages
Dry, crusty, cracked, and flaky skin as the condition progresses
Possible clearing of the patch center, creating a ring-like appearance

What distinguishes discoid eczema from other skin conditions? The hallmark of discoid eczema is its circular or oval shape, which can range from a few millimeters to several centimeters in size. These patches are often intensely itchy, particularly at night, and can become dry and cracked over time.

Signs of Infection in Discoid Eczema

In some cases, discoid eczema patches may become infected. How can you identify an infection in discoid eczema? Look for these signs:

Excessive fluid oozing from the patches
Development of a yellow crust over the patches
Redness, heat, swelling, and tenderness in the surrounding skin
Systemic symptoms like feeling sick, chills, or general unwellness

The Enigmatic Causes of Discoid Eczema

While the exact cause of discoid eczema remains unknown, several factors are believed to contribute to its development:

Dry Skin as a Primary Factor

Why is dry skin considered a significant factor in discoid eczema? Dry skin compromises the skin’s natural barrier function, making it more susceptible to irritation from substances that are typically harmless. This increased sensitivity can lead to the development of discoid eczema patches.

Potential Triggers and Associated Conditions

What can trigger an outbreak of discoid eczema? Several factors have been identified:

Minor skin injuries (e.g., insect bites, burns)
Certain medications (interferon, ribavirin, TNF-alpha blockers, statins)
Dry environments and cold climates
Contact dermatitis from irritants in cosmetics or toiletries

It’s worth noting that some individuals with discoid eczema have a history of atopic eczema, which is often associated with asthma and hay fever. However, unlike atopic eczema, discoid eczema doesn’t appear to have a strong genetic component.

Diagnosing Discoid Eczema: When to Seek Medical Advice

If you suspect you have discoid eczema, it’s crucial to consult a healthcare professional. But when should you see a doctor for discoid eczema?

When you notice persistent circular or oval patches on your skin
If the patches are intensely itchy or painful
When you observe signs of infection in the affected areas
If over-the-counter treatments prove ineffective

How is discoid eczema diagnosed? In most cases, a GP can diagnose discoid eczema through a physical examination of the affected skin. They may ask additional questions about your symptoms and medical history. In some instances, further tests may be necessary to rule out other conditions or identify potential triggers.

The Role of Dermatologists in Discoid Eczema Diagnosis

When might a GP refer you to a dermatologist for discoid eczema? Referral to a dermatologist may be necessary if:

The diagnosis is uncertain
Patch testing is required to identify potential allergens
The condition is severe or unresponsive to initial treatments
Specialized management is needed

Effective Treatment Strategies for Discoid Eczema

While discoid eczema is typically a chronic condition, various treatments can help manage symptoms and control flare-ups. What are the most effective treatments for discoid eczema?

Topical Treatments

The cornerstone of discoid eczema treatment involves topical applications:

Emollients: These moisturizers help prevent skin dryness and maintain the skin barrier.
Topical corticosteroids: Ointments and creams that can alleviate severe symptoms and reduce inflammation.
Topical calcineurin inhibitors: These may be prescribed for sensitive areas or when steroids are not suitable.

Systemic Treatments

In some cases, oral medications may be necessary:

Antihistamines: These can help reduce itching and improve sleep quality.
Oral antibiotics: Prescribed when there’s a secondary bacterial infection.
Systemic corticosteroids: Used in severe cases for short-term management.

Additional Therapies

What other treatments might be beneficial for discoid eczema?

Phototherapy: Controlled exposure to UV light can help in some cases.
Wet wrap therapy: This technique can provide relief for severe, widespread eczema.
Dietary changes: Identifying and avoiding food triggers may help some individuals.

Living with Discoid Eczema: Self-Care and Management

Managing discoid eczema extends beyond medical treatments. What can you do to manage discoid eczema at home?

Avoid irritants: Identify and steer clear of substances that trigger flare-ups.
Maintain skin hydration: Use emollients regularly to keep skin moisturized.
Practice gentle skincare: Use mild, fragrance-free products and avoid hot showers.
Manage stress: Stress can exacerbate symptoms, so find effective stress-management techniques.
Wear appropriate clothing: Choose soft, breathable fabrics that don’t irritate the skin.

The Importance of Consistency in Discoid Eczema Care

Why is consistency crucial in managing discoid eczema? Consistent care helps maintain skin health, prevent flare-ups, and minimize the impact of the condition on daily life. Regular use of prescribed treatments, coupled with good skincare habits, can significantly improve outcomes for those living with discoid eczema.

Discoid Eczema Prognosis: What to Expect

Understanding the long-term outlook for discoid eczema is essential for managing expectations and planning treatment strategies. How long does discoid eczema typically last?

Discoid eczema is often a chronic condition that can persist for weeks, months, or even years without treatment. It may also recur, often affecting the same areas that were previously involved. However, with proper management and treatment, many individuals can achieve significant symptom relief and extended periods of remission.

Potential Complications and Long-Term Effects

What are the potential long-term effects of discoid eczema?

Skin discoloration: Areas affected by discoid eczema may remain discolored even after the condition has cleared.
Skin thickening: Chronic inflammation can lead to lichenification, or thickening of the skin.
Increased susceptibility to infections: Damaged skin barrier can make the affected areas more prone to bacterial, viral, or fungal infections.
Psychological impact: Chronic skin conditions can affect self-esteem and quality of life.

Discoid Eczema vs. Other Types of Eczema: Understanding the Differences

Eczema encompasses a group of skin conditions characterized by dry, irritated skin. How does discoid eczema differ from other types of eczema?

Discoid Eczema vs. Atopic Dermatitis

What are the key differences between discoid eczema and atopic dermatitis?

Appearance: Discoid eczema forms distinct circular patches, while atopic dermatitis typically presents as more diffuse, irregularly shaped areas.
Distribution: Discoid eczema can occur anywhere on the body, while atopic dermatitis often affects specific areas like the creases of elbows and knees.
Age of onset: Atopic dermatitis often begins in childhood, while discoid eczema more commonly affects adults.
Genetic component: Atopic dermatitis has a strong genetic link, whereas discoid eczema doesn’t appear to run in families.

Discoid Eczema vs. Contact Dermatitis

How can you distinguish between discoid eczema and contact dermatitis?

Cause: Contact dermatitis is triggered by direct contact with an irritant or allergen, while the cause of discoid eczema is often unclear.
Pattern: Contact dermatitis typically affects areas that have come into contact with the triggering substance, while discoid eczema forms distinct circular patches.
Resolution: Contact dermatitis often resolves when the irritant is removed, whereas discoid eczema tends to be more persistent.

Discoid Eczema vs. Psoriasis

What distinguishes discoid eczema from psoriasis?

Appearance: Psoriasis typically presents as thick, red patches covered with silvery scales, while discoid eczema forms coin-shaped, often oozing patches.
Distribution: Psoriasis commonly affects elbows, knees, and scalp, while discoid eczema can occur anywhere on the body.
Associated symptoms: Psoriasis can affect nails and joints, which is not typical of discoid eczema.

Prevention Strategies for Discoid Eczema

While it may not be possible to prevent discoid eczema entirely, several strategies can help reduce the risk of flare-ups and manage the condition effectively. What are some key prevention strategies for discoid eczema?

Maintaining Skin Hydration

How can proper skin hydration help prevent discoid eczema flare-ups?

Use emollients daily, even when the skin appears healthy
Apply moisturizers immediately after bathing to lock in hydration
Choose products that are fragrance-free and suitable for sensitive skin
Consider using a humidifier in dry environments to add moisture to the air

Identifying and Avoiding Triggers

What steps can you take to identify and avoid discoid eczema triggers?

Keep a diary to track potential triggers, including environmental factors, foods, and skincare products
Perform patch tests before using new skincare or cosmetic products
Avoid harsh soaps, detergents, and other irritating chemicals
Protect your skin from extreme weather conditions

Lifestyle Modifications

What lifestyle changes can help prevent discoid eczema flare-ups?

Manage stress through relaxation techniques, exercise, or counseling
Maintain a balanced diet rich in anti-inflammatory foods
Stay hydrated by drinking plenty of water
Avoid scratching or rubbing affected areas
Wear soft, breathable clothing to minimize skin irritation

The Future of Discoid Eczema Research and Treatment

As our understanding of discoid eczema continues to evolve, researchers are exploring new avenues for treatment and management. What are some promising areas of research in discoid eczema?

Targeted Therapies

How might targeted therapies improve discoid eczema treatment?

Biologics: These drugs target specific components of the immune system involved in inflammation
JAK inhibitors: These medications block specific enzymes involved in the inflammatory response
Microbiome-based treatments: Targeting the skin’s microbiome may help restore balance and reduce inflammation

Advanced Diagnostic Tools

What new diagnostic tools are being developed for discoid eczema?

Biomarker testing: Identifying specific markers in the blood or skin that indicate disease activity or predict treatment response
Imaging techniques: Advanced imaging methods may help visualize skin changes more accurately
Genetic testing: Understanding genetic factors may lead to more personalized treatment approaches

Patient-Centered Care Approaches

How are patient-centered care approaches evolving in discoid eczema management?

Telemedicine: Remote consultations and monitoring can improve access to care
Mobile apps: Tools for tracking symptoms, triggers, and treatment adherence
Patient support groups: Connecting individuals with discoid eczema for shared experiences and coping strategies
Integrated care models: Combining dermatology, allergy, and mental health support for comprehensive management

As research progresses, individuals with discoid eczema can look forward to more effective, personalized treatment options and improved quality of life. Staying informed about these advancements and working closely with healthcare providers will be key to optimizing management strategies in the future.

Discoid eczema | nidirect

Discoid eczema, also known as nummular or discoid dermatitis, is a long-term skin condition. It causes skin to become itchy, reddened, swollen and cracked in circular or oval patches. See your pharmacist or GP if you think you may have discoid eczema so they can recommend a suitable treatment.

Symptoms of discoid eczema

Circular or oval patches of eczema

Circular or oval patches of eczema can affect any part of the body, although they don’t usually affect the face or scalp.

They start as a group of small red spots or bumps on the skin which join up to form larger pink, red or brown patches that can range from a few millimetres to several centimetres in size.

Blistering

At first, these patches of eczema are often swollen, blistered (covered with small fluid-filled pockets) and ooze fluid.

Itchiness and pain

The patches also tend to be very itchy, particularly at night.

Dry, crusty, cracked and flaky skin patches

Over time, the patches may become dry, crusty, cracked and flaky. the centre of the patch also sometimes clears, leaving a ring of discoloured skin that can be mistaken for ringworm.

Discoid eczema causes circular or oval patches of eczema on the skin

You may just have one patch of discoid eczema, but most people get several patches. The skin between the patches is often dry.

Patches of discoid eczema can sometimes become infected.

Signs of an infection can include:

the patches oozing a lot of fluid
a yellow crust developing over the patches
the skin around the patches becoming red, hot, swollen, and tender or painful
feeling sick
chills
feeling unwell

When to get medical advice

See your pharmacist or GP if you think you may have discoid eczema so they can recommend a suitable treatment.

You should also seek medical advice if you think your skin may be infected. You may need treatment.

Your GP should be able to make a diagnosis just by examining the affected areas of skin. In some cases they may also ask questions or arrange some tests to rule out other conditions.

Your GP may refer you to a dermatologist (a doctor who specialises in managing skin conditions) if they’re unsure of the diagnosis or if you need patch testing.

Causes of discoid eczema

The cause of discoid eczema is unknown, although it may occur as a result of having particularly dry skin.

Dry skin means your skin can’t provide an effective barrier against substances that come into contact with it. This could allow a previously harmless substance, such as soap, to irritate (damage) your skin.

It’s important to look carefully at all the chemicals in cosmetics and toiletries that may have come into contact with your skin. Contact dermatitis, a type of eczema caused by coming into contact with a particular irritant, may have a role in discoid eczema.

Some people with discoid eczema also have a history of atopic eczema, which often occurs in people who are prone to asthma and hay fever. However, unlike atopic eczema, discoid eczema doesn’t seem to run in families.

Other possible triggers

An outbreak of discoid eczema may sometimes be triggered by a minor skin injury, such as an insect bite or a burn.

Some medicines may also be associated with discoid eczema, as patches of eczema can appear in people taking:

interferon and ribavirin – when they’re used together to treat hepatitis C
tumour necrosis factor-alpha (TNF-alpha) blockers – used to treat some types of arthritis
statins (cholesterol-lowering medication) – which can cause dry skin and rashes

Dry environments and cold climates can make discoid eczema worse, and sunny or humid (damp) environments may make your symptoms better.

Treating discoid eczema

Discoid eczema is usually a long-term problem. But medications are available to help relieve the symptoms and keep the condition under control.

Without treatment, discoid eczema can last for weeks, months or even years. It may also keep recurring – often in the same area that was affected previously.

Treatments used include:

emollients – moisturisers applied to the skin to stop it becoming dry
topical corticosteroids – ointments and creams applied to the skin that can help relieve severe symptoms
antihistamines – medications that can reduce itching and help you sleep better

There are also things you can do yourself to help, such as avoiding all the irritating chemicals in soaps, detergents, bubble baths and shower gels.

Additional medication can be prescribed if your eczema is infected or particularly severe.

Occasionally, areas of skin affected by discoid eczema can be left permanently discoloured after the condition has cleared up.

Other types of eczema

Eczema is the name for a group of skin conditions that cause dry, irritated skin. Other types of eczema include:

atopic eczema (also called atopic dermatitis) – the most common type of eczema, it often runs in families and is linked to other conditions such as asthma and hay fever
contact dermatitis – a type of eczema that occurs when the body comes into contact with a particular substance
varicose eczema – a type of eczema that most often affects the lower legs and is caused by problems with the flow of blood through the leg veins

The telltale signs of the fungal infection ringworm, include an area of the skin that may be:

red
itchy
scaly
bumpy
roughly circular

It may also have a slightly raised border. If the border of the patch slightly raises and extends outward, roughly forming a circle, it might resemble a worm or a snake.

Ringworm is actually caused by mold-like parasites — no actual worm is involved. If caught early it can be cleared with an antifungal cream or ointment. If it covers a large area of skin, your doctor may prescribe an antifungal medicine.

These signs of ringworm can be different for different people and they’re similar to other conditions. So, if that red circle on your skin isn’t ringworm, what could it be?

Like ringworm, eczema is often first noticed as an itchy, red patch. Other symptoms may include:

dry skin
rough or scaly patches of skin
swelling
crusting or oozing

Unlike ringworm, there’s currently no cure for eczema. But symptoms can be managed with:

lifestyle changes
over-the-counter remedies
prescription topicals
immunosuppressants

Because it often looks like a ring of small skin-colored, pink or red bumps, granuloma annulare might be mistakenly identified as ringworm. The diameter of the rings can be up to 2 inches.

While ringworm is a fungal infection, it’s not clear was causes granuloma annulare.

It’s sometimes triggered by:

minor skin injuries
insect or animal bites
vaccinations
infections

Granuloma annulare is typically treated with:

corticosteroid creams or injections
oral medications, such as antibiotics or drugs to prevent immune system reactions
freezing with liquid nitrogen
light therapy

Psoriasis could be mistaken for ringworm because of the itchy red patches and scales that are symptoms of the condition.

Unlike ringworm, psoriasis is not a fungal infection, it’s a skin condition that accelerates the skin cell life cycle.

Psoriasis symptoms may include:

red patches with silvery scales
itching, soreness, or burning
cracked, dry skin

While ringworm can be cured with antifungal medication, there’s currently no cure for psoriasis. The symptoms of psoriasis can be addressed with a variety of treatments including:

topical steroids
vitamin D analogues
retinoids
calcineurin inhibitors
cyclosporine
light therapy

With its itchy, red rash, contact dermatitis might be confused with ringworm. Contact dermatitis occurs when your body reacts to a chemical, such as a skin care product or detergent.

Other symptoms might include:

dry, scaly, cracked skin
swelling or tenderness
bumps or blisters

Like ringworm, a key to treating contact dermatitis is avoidance. With ringworm, a contagious fungal infection, you avoid infected people, animals, and objects. With contact dermatitis you identify and avoid the substance that triggers the condition.

Treatment might include steroid ointments or creams and oral medications such as antihistamines or corticosteroids.

A bullseye rash is a common sign of Lyme disease. Because of its circular appearance, it can be mistaken for ringworm.

Lyme disease is caused by a bite from a black-legged tick.

Other symptoms of Lyme disease may include flu-like symptoms and a spreading rash that’s itchy or painful.

It’s important to treat Lyme disease as soon as possible. Treatment commonly includes oral or intravenous antibiotics.

Pityriasis rosea typically starts with a round or oval, slightly raised, scaly patch on your chest, abdomen, or back. Because of its shape, the first patch (herald patch) might be erroneously thought to be ringworm. The herald patch is usually followed by smaller spots and itching.

Although the exact cause of pityriasis rosea hasn’t been determined, it’s thought to be triggered by a viral infection. Unlike ringworm, it’s not believed to be contagious.

Pityriasis rosea commonly goes away on its own in 10 weeks or less and is treated with nonprescription medications and remedies to relieve itching.

If the itching is unbearable or it doesn’t disappear in an appropriate amount of time, your doctor may prescribe:

antihistamines
antiviral drugs
corticosteroids

Although a circular or ring-like rash could be ringworm, it could also be a ringworm look alike.

If you notice a circular rash on yourself or a child, a visit to the doctor for an accurate diagnosis is often warranted. Your doctor might refer you to a dermatologist. The Healthline FindCare tool can provide options in your area if you don’t already have a dermatologist.

If, following the doctor’s visit, the rash doesn’t clear up as expected, update your doctor to see if you need a new diagnosis. Many skin conditions have similar appearances and symptoms, so the original diagnosis may have been inaccurate.

Plaques on the skin: the causes of occurrence, in what diseases they occur, diagnosis and methods of treatment.
Definition

A plaque is a pathological element with clear edges that rises above the skin surface or merges with it, more than 5 mm in size.
In dermatology, many types of plaques are distinguished – about 70 diseases occur with the formation of these elements, which makes the plaque one of the most common rashes.
Varieties of plaques

The shape of the plaques are round, oval and irregular in shape. Over time, the shape, surface and appearance of this element may change.
Due to the occurrence of plaques, they can be both a manifestation of skin diseases and a symptom of diseases of internal organs and systems (autoimmune reactions, liver diseases, oncological processes, allergic reactions).
Plaques are dry, smooth, red, brown, gray-white, etc.
Possible causes of plaques
Dry plaques on the skin in adults can be a manifestation of the following diseases:
1. Fungal infection of the skin, accompanied by plaques with severe itching.
2. Allergic reactions are characterized by the appearance on the skin of smooth dry plaques, pink spots, blisters, which are very itchy and cause severe discomfort. They can develop both when the skin comes into contact with the allergen, and when it gets on the mucous membranes (for example, with urticaria, hay fever, food and contact allergies).
3. Psoriasis is a chronic non-infectious skin disease in which scaly dry plaques form on the elbows, knees, scalp, prone to fusion and accompanied by mild itching.
1. Dry plaques form on the skin if it is exposed to stress for a long time with the loss of its protective functions.
2. Diseases of the digestive tract, accompanied by malabsorption syndrome (impaired absorption of vitamins and trace elements in the small intestine), chronic diseases of the liver and other organs, in which substances that are not normally present in the dermis accumulate, also lead to the appearance of dry plaques.
3. Solar keratoma is a precancerous condition, which is characterized by the presence of many light grayish plaques on the skin.
The appearance of red plaques on the skin indicates their good blood supply. Possible causes of this condition may be the following nosologies:
1. Drug toxidermia is an allergic reaction accompanied by the appearance of elements in the form of plaques on the skin. In severe cases, Lyell’s syndrome or Stevens-Johnson syndrome, toxic epidermal necrolysis, may develop.
1. Dühring’s dermatitis (herpetiform) is a chronic skin disease with no established etiology, which is characterized by recurrent appearance of a rash of various morphologies on the skin, accompanied by severe skin itching and burning.
2. Mycosis fungoides is a primary T-cell lymphoma of the skin, a malignant lymphoid lesion, primarily of the skin. Itchy red plaques appear on the skin, resembling eczema. In the initial stages, they respond well to treatment with hormonal ointments, but the disease itself requires more complex therapy.
1. In children, the appearance of red spots and plaques on the skin is most often associated with an allergic reaction to food.
Brown plaques occur when melanin is deposited in the affected area of the dermis, which causes a brown (dark) color. Possible causes may be the following diseases:
1. Becker’s nevus – an anomaly in the development of the dermis, when dark plaques with an uneven surface appear on the skin, on which hair can begin to grow over time.
2. Pigmentary nevus – “birthmark”, may rise above the skin, has a brown or dark color.
3. Melanoma is the most malignant skin tumor characterized by rapid metastasis. It develops mainly from nevi and moles. If the nature of the surface, the boundaries of the mole change, its size increases, bleeding occurs, you should immediately contact a dermatologist or oncologist to exclude the development of melanoma.
4. Basal cell skin cancer is more often localized on the head, face, neck, does not metastasize, is characterized by slow growth.
5. Senile keratoma occurs in elderly people, most likely due to a lack of vitamins, an abundance of animal fats consumed, skin sensitivity to ultraviolet radiation due to a violation of its protective functions. Typical localization – face, neck, open areas of the body.
6. Seborrheic keratoma is a yellowish plaque on the skin that, over time, transforms into a dark brown growth that tends to peel, itch, crack, bleed, and can serve as an entryway for infection.
Which doctors to contact
With the formation of plaques on the skin, it is necessary to contact a dermatologist to determine the causes of the appearance of this element of the rash.
Diagnosis and testing for plaques

For the diagnosis of fungal skin lesions, scraping from the affected area is used for subsequent microscopic examination.
The development of an allergic reaction requires seeking medical help to identify the allergen, prescribing antihistamines, and sometimes hormonal drugs. In clinical cases of allergy, along with skin tests, analyzes are performed using various sets of common allergens and triggers: a panel for respiratory allergens, for food allergens, and for a combination of both.

What should I do if plaques appear on the skin?

Any newly appeared neoplasms should be shown to a dermatologist. Their cosmetic removal without prior consultation with a specialist is fraught with serious consequences.
In addition, there are symptoms that require immediate medical attention:
- change in the shape of the plaque – the edges have become uneven;
- change in the surface of the plaque – cracks, ulcerations appeared;
- change in the size of the plaque – it began to grow rapidly above the surface of the skin or actively spread through it;
- discoloration of the plaque – in cases of malignancy, an uneven color of the formation is usually observed with areas of darker and lighter shades;
- the appearance of bleeding – both contact and spontaneous;
- enlargement of regional (nearby) lymph nodes.
Plaque treatment

When plaques of an allergic nature appear on the skin, antihistamines are prescribed, in cases of a severe course of the disease, glucocorticosteroids. In addition, it is important to follow a hypoallergenic diet.
Mycotic plaques require antifungal drugs, both local (ointments, creams) and systemic (tablets). Taking these drugs is associated with a high risk of side effects, and therefore it is possible only after consulting a doctor, accurate verification of the diagnosis and confirmation of the etiology of the disease.
Treatment of psoriasis is multi-stage and complex, it involves constant monitoring by a rheumatologist, taking cytostatics and other drugs, using ointments and shampoos to improve skin condition, using antihistamines to reduce itching, including physiotherapy and a hypoallergenic diet in the treatment regimen.
When confirming the presence of diseases of the gastrointestinal tract, properly selected therapy can stop the appearance of new plaques on the skin, as well as prevent the development of complications of the underlying disease.

Dry spots on the skin: three common dermatological diseases
July 5, 2020
Dry spots on the skin are a common dermatological symptom that can indicate both a temporary failure and a violation of the barrier functions of the epidermis, and a skin disease. It all depends on the size of the spots, the clarity of their boundaries, as well as the duration of their presence on the skin.
The causes of dryness can be divided into two large groups:
- non-specific – allergic reactions to household chemicals, laundry soap, cosmetic products, dehydration due to cold and wind;
- specific – then the spots become a manifestation of dermatological diseases.
Sometimes a person may notice that dry spots appear on his skin after a certain event occurs, for example, after washing clothes with his hands. Then the reason is obvious and easy to eliminate. But if dry spots on the skin do not go away, itch, peel off, you should consult a doctor.
Dry spots with scales
Pink raised dry spots on the body and head may indicate psoriasis. With this dermatological pathology in humans, raised plaques appear on the skin – psoriatic papules. They protrude above the surface of the skin, cause intense itching and flake, tend to spread and merge.
Psoriasis is a chronic autoimmune disease in which rashes are most often localized on the elbows, head, knees and groin. Dry pink spots covered with white scales are foci of chronic inflammation. Under the influence of internal autoimmune processes, epidermal cells divide several times faster than necessary. As a result, small scales are constantly separated from dying skin cells.
Atopic dermatitis and its difference from psoriasis
Atopic dermatitis can also cause dry patches on the body. And as with psoriasis, they cause itching. Due to the increased sensitivity of the skin to environmental factors, the mechanisms of its self-regulation are violated, including the barrier function. That is, an allergy is a trigger for atopic dermatitis, but the tendency to such a skin reaction is genetically laid down.
Most often, atopic dermatitis occurs in children. The disease has a chronic course, when exacerbations are replaced by periods of remission. Here are the typical signs of atopic dermatitis:
- dry skin;
- peeling and redness of the eyelids;
- dry skin-colored plaques on the trunk and extensor areas of the body;
- cracks.
It is difficult for a person who does not have a medical education to distinguish psoriasis from atopic dermatitis, but a doctor can easily make a differential diagnosis. There are several differences that may speak in favor of a particular pathology. Atopic dermatitis often affects children, psoriasis can debut in adulthood. Psoriatic plaques are raised above the skin, and scales can be seen. Dry spots in atopic dermatitis are flat. It is also important to consider typical localization.

Dry eczema
Sometimes white, dry, scaly patches on the skin of the legs can indicate dry eczema. With this disease, dryness and tightness of the skin first occurs, then peeling and unbearable itching join, cracks may occur. In addition to the legs, the hands, the space between the fingers, and even the face are often affected.
