About Varicose Eczema

Overview

Varicose eczema, also known as venous eczema, venous stasis, gravitational dermatitis, or stasis dermatitis, is a skin condition that affects the lower legs and ankles. It occurs in individuals with varicose veins or insufficient blood flow in the lower body.

Varicose eczema is more common in women and typically affects people over the age of 50. The condition is characterized by skin changes such as dryness, scaling, inflammation, and shiny-looking skin. Other symptoms may include hyperpigmentation (darkening of the skin), leg pain or aching, swelling in the ankles, warmth in the legs, cracks or crusting of the affected skin, and blisters that may ooze fluid.

If left untreated, varicose eczema can lead to complications such as ulcers. It is important to consult a healthcare professional for an accurate diagnosis and appropriate management.

Causes and Risk Factors

Varicose eczema occurs due to the following causes:

Venous insufficiency: Weak one-way valves in the leg veins lead to improper blood flow from the limbs to the heart. This causes blood to pool in the leg veins and leak into surrounding tissues.
Inflammation: The immune system reacts to the leaked blood, resulting in inflammation and the appearance of eczema symptoms.

Non-modifiable risk factors for varicose eczema cannot be controlled or changed. They include:

Age: It is more common in middle-aged and older adults, with a higher prevalence in those over 70 years old.
Varicose veins: Having varicose veins increases the risk of developing varicose eczema.
Health conditions: Certain conditions that affect blood flow or limb health, such as high blood pressure, phlebitis (inflamed veins), cellulitis, deep vein thrombosis, leg surgery, heart failure, and kidney disease or failure, can elevate the risk.

Modifiable risk factors for varicose eczema can be influenced by individual habits and lifestyle. They include:

Obesity: Being overweight or obese puts extra pressure on the veins in your legs, making it harder for blood to flow properly. This can contribute to the development of venous eczema.
Sedentary lifestyle: Lack of physical activity and prolonged periods of sitting or standing can impair blood circulation in the legs and increase the risk of developing venous eczema. Regular exercise and avoiding long periods of sitting or standing can help improve circulation.
Smoking: Smoking damages blood vessels and impairs circulation, which can increase the risk of developing venous eczema. Quitting smoking can help improve overall vascular health.
High blood pressure: Uncontrolled high blood pressure can put strain on blood vessels and contribute to poor circulation in the legs, increasing the risk of venous eczema. Managing blood pressure through lifestyle changes and medication can help reduce this risk.
Leg injuries or surgeries: Previous leg injuries or surgeries can damage veins and disrupt normal blood flow, increasing the likelihood of developing venous eczema.

Remember, it's important to consult with your healthcare professional for personalized advice of your risk factors for developing varicose eczema.

Symptoms

The most common early symptoms of varicose eczema include:

Dry, scaly rash
Red or discolored, inflamed, and slightly shiny skin
Hyperpigmentation or discolored skin (usually a rust or brown color)
Aching legs
Ankle swelling that tends to get better when you sleep but swells when you wake up
Warm feeling in your legs, although your skin remains cool when you touch it

As varicose eczema progresses or becomes more severe, additional symptoms may occur, including:

Crusty or cracked skin
Weeping eczema or oozing, fluid-filled blisters on the skin
Swelling in the legs that persists
Hard and thickened skin
Tender and painful skin
Red to red-brown or violet-brown colored skin

In some cases, varicose eczema can lead to the development of varicose leg ulcers or open sores near the ankle. It's important to seek medical attention for proper diagnosis and treatment.

Diagnosis

To diagnose varicose eczema, healthcare providers may perform the following examinations, tests, and procedures:

Medical history: The healthcare provider will ask about the patient's medical history, including any history of chronic venous insufficiency and other skin conditions.
Physical examination: The healthcare providert will conduct a physical examination to look for hallmark skin changes and ask about symptoms. These findings alone are often enough to diagnose varicose eczema.

Additional tests may be needed to confirm the diagnosis or exclude other types of skin conditions. These tests may include:

Skin patch test: This test involves exposing the patient's skin to different potential allergens to determine if their eczema is caused by allergic contact dermatitis.
Doppler ultrasound: This imaging test uses sound waves to create pictures that help doctors measure blood flow through the patient's limbs. It can help assess the extent of chronic venous insufficiency.
Ankle brachial index test: This test measures blood flow to the legs and looks for areas where blood flow is fully or partly blocked.
Cardiac tests: Electrocardiograms (ECG or EKG), chest X-rays, echocardiograms, and other tests that measure heart function may be performed.
Artery studies: These tests measure blood flow in the arteries and can check for conditions that may contribute to varicose eczema.
Thermography: This imaging technique uses infrared cameras to measure skin temperature. It can help identify areas of inflammation and assess disease severity.
Phlebodynamometry: This test measures changes in limb volume to evaluate venous function.

It's important to consult with a healthcare professional who can provide personalized advice based on your individual situation.

Treatment Options

The goals of treatment for varicose eczema are to ease skin conditions and boost blood flow. Treatment options and how they work to achieve these goals include:

Medications:

Corticosteroid creams: These creams can be used on a short-term basis to reduce inflammation and quell inflamed skin.
Topical antibiotic: If an infection develops in the affected limb(s), a topical antibiotic may be prescribed to treat it.
Topical anti-inflammatory medications: Some experimental studies have shown a potential benefit with topical phosphodiesterase anti-inflammatory medications.

Therapies:

Wet dressings: These dressings are soaked in a special solution and can be used to treat weeping eczema. They help soothe the skin and promote healing.
Compression garments: Graduated compression stockings or an Unna boot with zinc-oxide dressing built in can be worn to boost blood flow and lessen pressure in the veins.
Phototherapy: This type of light therapy exposes the affected skin to UV light, which helps reduce symptoms of Varicose Eczema.

Therapeutic procedures:

Corticosteroid injections: In severe cases where creams have not been effective, corticosteroid injections may be given directly into the affected skin area. This helps reduce inflammation.

Self-care and health behavior changes:

Avoiding triggers: It is important to identify and avoid triggers that can cause flare-ups of varicose eczema. This may include avoiding certain fabrics or chemicals that irritate the skin.
Moisturizing the skin: Keeping the skin hydrated is crucial in managing dryness. Moisturizers should be applied immediately after bathing to minimize water loss.
Elevating legs: Raising your legs above heart level whenever possible can help improve blood circulation.

It's important to note that these treatments should be discussed with your healthcare professional as they can provide personalized advice based on your individual situation.

Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for side effect information.
