Eczema, a term often used to describe a group of medical conditions causing inflammation and skin irritation, affects millions of individuals worldwide. Characterised by itchy, dry, and red skin that may blister or crack, eczema’s impact ranges from mild discomfort to severe physical and psychological distress. There are several types of eczema, including atopic dermatitis, contact dermatitis, dyshidrotic eczema, nummular eczema, and seborrheic dermatitis, each with its unique triggers, symptoms, and treatment protocols.
Among the pantheon of skin conditions classified under the umbrella of eczema, one stands out due to its unique set of causes and characteristics—varicose eczema, also known as venous, gravitational, or stasis eczema. Predominantly affecting the lower legs of adults, especially those over 50, varicose eczema is closely linked to impaired blood flow, a condition often manifesting as varicose veins.
While it shares the broader family of eczema’s propensity for causing red, itchy, and inflamed skin, varicose eczema presents a distinct clinical picture regarding its causes, symptomatology, and management.
Understanding Eczema
Eczema is a broad term encompassing a variety of inflammatory skin conditions that result in red, itchy, and often scaly rashes. While it can occur at any age and affect any part of the body, it most frequently appears in early childhood, particularly on the face, hands, and in the bends of the elbows and knees. Eczema is generally characterised by periods of flare-ups, where symptoms worsen, and remissions, where symptoms improve or disappear.
Different Types of Eczema
There are several distinct types of eczema, each with unique triggers, symptoms, and affected areas:
Atopic Dermatitis:
This is the most common form of eczema, often starting in childhood. Symptoms typically include dry skin, itching, and red to brownish-grey patches. It’s associated with a higher risk of developing other allergic conditions like hay fever and asthma.
Contact Dermatitis:
This type is triggered by contact with a substance that irritates the skin or causes an allergic reaction. Symptoms include a red rash, itching, dry, cracked, scaly skin, and, in severe cases, blisters and burns.
Dyshidrotic Eczema:
This type affects the fingers, palms of the hands, and soles of the feet. It causes itchy, scaly patches of skin that flake or become red, cracked, and painful. It’s more common in women than men.
Nummular Eczema:
Also known as discoid eczema, this form causes round, coin-shaped spots to form on the skin. These spots are often itchy and well-defined.
Seborrheic Dermatitis:
This type primarily affects your scalp, causing scaly patches, red skin, and stubborn dandruff. In infants, it’s known as cradle cap.
Each type of eczema has its unique characteristics, but they all share the common symptom of itchy, inflamed skin.
Varicose Eczema
Varicose eczema, also known as venous, gravitational, or stasis eczema, is a chronic, long-term skin condition that affects the lower legs. Its name derives from its common association with varicose veins, which occur when the small valves inside the veins stop working correctly. This condition is characterised by skin that becomes swollen, thickened, and itchy, and it may also change colour, usually dark brown or purple. Over time, the skin may become dry and flaky and can break down to form ulcers if not appropriately managed.
Varicose eczema is more commonly seen in women, and its prevalence increases with age. It is estimated to affect up to 20% of people over 70. It is also significantly more common in people with a history of deep vein thrombosis (DVT) or varicose veins.
Risk Factors and Common Causes of Varicose Eczema
The primary cause of varicose eczema is increased pressure in the veins of the lower legs. This is often due to varicose veins, where veins, usually in the legs, become enlarged and twisted. Other risk factors include:
- Age: Varicose eczema is more common in older adults, as the valves in the veins may become weaker over time.
- Gender: Women are more likely to develop varicose eczema, possibly due to hormonal factors.
- Mobility: People who stand or sit for long periods or who have limited mobility are at increased risk due to poor blood circulation in the lower legs.
- Obesity: Excess weight can put additional pressure on the veins, increasing the risk.
- History of DVT: A history of deep vein thrombosis can damage the valves in the veins, leading to increased pressure.
Understanding the risk factors and causes of varicose eczema can help in its prevention and management and provide a basis for its differentiation from other forms of eczema.
Symptoms and Diagnosis of Varicose Eczema
Varicose eczema presents a unique set of symptoms that evolve over time. The skin changes occur predominantly in the lower legs and can include:
Skin Discolouration:
Early signs of varicose eczema often include a change in the skin colour, usually dark brown or purple. This is due to the leakage of small amounts of blood from the veins into the skin.
Itching:
The affected area may become intensely itchy, leading to discomfort and, in some cases, sleep disturbance.
Swelling:
The skin may become swollen, particularly after long periods of standing or sitting.
Dry, Flaky Skin:
The skin often becomes dry and flaky and may feel tight.
Thickened Skin:
Over time, the skin may become thickened and hard, a condition known as lipodermatosclerosis.
Pain or Tenderness:
Some people experience pain or tenderness in the affected area.
Eczema:
Red, scaly, itchy rash indicative of eczema may appear over areas of discolouration.
Venous Eczema:
In advanced cases, the skin may break down to form ulcers, particularly near the ankles. These venous leg ulcers can be challenging to heal and require medical attention.
How Varicose Eczema is Diagnosed
In the UK, varicose eczema is typically diagnosed based on the appearance of the skin and the patient’s medical history. A general practitioner (GP) or a dermatologist will examine the skin and ask about any symptoms. They may also inquire about any varicose veins or deep vein thrombosis history.
While the diagnosis of varicose eczema can often be made based on a physical examination alone, further investigations may be needed to assess the condition of the veins. This could include an ultrasound to evaluate the blood flow and pressure in the veins of the legs.
It’s essential to seek medical advice if you notice any changes in your skin, as early diagnosis and treatment can help manage the symptoms of varicose eczema and prevent complications such as skin ulcers.
Varicose Eczema vs. Other Eczemas
Varicose eczema’s primary cause is increased pressure in the veins of the lower legs, often due to varicose veins or a history of deep vein thrombosis. This contrasts with other forms of eczema, which various factors can trigger. For example, atopic dermatitis is linked to a malfunctioning immune system and is often seen in people with a history of allergies. Contact dermatitis, on the other hand, occurs when the skin comes into direct contact with an allergen or irritant.
Comparison of Symptoms and Affected Areas
While all forms of eczema cause itchy, inflamed skin, the areas affected and specific symptoms can differ. Varicose eczema primarily affects the lower legs, causing skin discolouration, swelling, and in severe cases, skin ulcers. In contrast, atopic eczema often affects areas where the skin folds, like behind the knees or inside the elbows, and is characterised by red to brownish-grey patches. Contact dermatitis can occur anywhere on the body that has come into contact with an irritant, leading to a red rash, itching, and potentially blisters.
Differences in Demographic Prevalence
Varicose eczema tends to affect older adults, with a higher prevalence in those over 50 and is more common in women. This contrasts with atopic dermatitis, which usually starts in childhood and affects both genders equally. Dyshidrotic eczema, in contrast, is more common in women than men.
Differences in Diagnostic Criteria
Varicose eczema is typically diagnosed by a physical examination and a patient’s medical history, with further investigations like ultrasound occasionally required. This is unlike contact dermatitis, where patch testing might be used to identify the specific allergen causing the reaction. Atopic eczema, on the other hand, is often diagnosed based on a combination of symptoms, medical history, and in some cases, allergy tests.
Treatment and Management of Varicose Eczema (NICE)
The National Institute for Health and Care Excellence (NICE) provides evidence-based guidelines for treating various health conditions in the UK, including varicose eczema. The management of varicose eczema primarily aims to treat the symptoms, prevent flare-ups, and manage any underlying causes like varicose veins.
Treatments Including Self-Care, Medications, and Surgical Options
Self-care:
This involves daily skincare to keep the skin moisturised, avoiding irritants that could worsen the condition, and using compression stockings to improve blood flow in the legs. Regular exercise and elevating the legs when sitting can also help.
Medications:b
Topical corticosteroids may reduce inflammation during flare-ups, while emollients (moisturisers) should be used regularly to keep the skin soft and supple. In cases of infection, topical or oral antibiotics may be prescribed.
Surgical Options: If varicose eczema is linked to varicose veins, and these veins are causing significant symptoms or complications, procedures to treat the veins might be considered. These can include endothermal ablation, where heat is used to seal the affected veins, or sclerotherapy, which uses foam to close the veins.
Managing Underlying Varicose Veins
Managing underlying varicose veins is crucial in treating varicose eczema, as this condition is often the root cause of the increased pressure in the veins of the lower legs. If left untreated, varicose veins can continue to cause symptoms and potentially lead to complications like skin ulcers. Therefore, part of the comprehensive management of varicose eczema may involve treating varicose veins, either through self-care measures like using compression stockings or through medical procedures if necessary.
Living with Varicose Eczema
Living with varicose eczema can require some adjustments to your daily routine. Here are a few practical tips to help manage the condition:
- Skincare Routine: Regularly moisturise your skin with emollients to keep it hydrated and reduce dryness and itching. Avoid using soaps or detergents that could dry out the skin further.
- Compression Stockings: Use properly fitted compression stockings during the day to help improve blood flow in your legs and reduce swelling.
- Elevation: Try to elevate your legs whenever possible, especially when sitting or sleeping. This can help reduce the pressure in your veins and minimise swelling.
- Exercise: Regular exercise such as walking or swimming can improve your circulation and help manage symptoms.
- Healthy Weight: Maintaining a healthy weight can reduce the pressure on your veins and help manage symptoms.
Mental Health
Living with a chronic skin condition like varicose eczema can be challenging and may impact your mental health. If you’re feeling anxious or depressed, it’s important to seek help:
- Talk About It: Don’t hesitate to talk to your healthcare provider about your feelings. They can provide resources and refer you to a mental health specialist.
- Support Groups: Connecting with others who are also living with eczema can provide comfort, reduce feelings of isolation, and provide practical tips. Organisations like the National Eczema Society offer resources and support groups in the UK.
- Self-care: Take time each day to relax and do activities you enjoy. Mindfulness, meditation, and gentle exercise can all help reduce stress and improve your mental wellbeing.
Remember, it’s just as important to take care of your mental health as it is to manage your physical symptoms.
In Summary
Compared to other forms of eczema, varicose eczema stands out due to its unique causes, symptoms, affected areas, and demographic prevalence. Understanding these differences is crucial to ensure accurate diagnosis and effective treatment. Management of varicose eczema not only involves treating the symptoms and addressing the underlying cause – the varicose veins.
Living with varicose eczema can have challenges, but it can be effectively managed with the right lifestyle changes, treatment approaches, and mental health support. Individuals must work closely with their healthcare provider to develop a comprehensive treatment plan.
In conclusion, understanding the critical differences between varicose eczema and other types of eczema is vital for those living with the condition and healthcare professionals to ensure appropriate and effective management of this chronic skin condition.
