Stasis Dermatitis (Venous Eczema): Symptoms, Causes, and Treatment

Stasis dermatitis, also called venous eczema or varicose eczema, is inflammation on the lower legs linked to poor return of blood through the veins. It can cause itch, scale, swelling, discoloration, skin hardening, and sometimes wounds. Care usually addresses both the skin and the circulation.

Medical information: This article is educational and cannot diagnose a leg rash or recommend an individual compression level. New, painful, or worsening leg changes should be assessed by a clinician, especially before using compression garments.

What stasis dermatitis means

Stasis dermatitis is a type of eczema on the lower legs that develops in association with chronic venous insufficiency, when blood does not return efficiently through the leg veins. It is also called venous eczema, varicose eczema, gravitational eczema, or venous stasis dermatitis. The skin inflammation is linked to pressure and fluid buildup in the tissues; it is not simply a surface dryness problem.

Healthy leg veins use one-way valves and the calf muscles to move blood upward toward the heart. If vein valves are damaged or do not close well, blood can pool in the lower legs. Pressure rises, fluid can seep into nearby tissue, and the skin may become swollen, itchy, inflamed, or discolored. A previous deep vein thrombosis, varicose veins, reduced mobility, or chronic leg swelling can be part of the history.

Stasis dermatitis often affects one or both ankles and lower legs. It may appear as dry, scaly, itchy patches, or as red, blistered, crusted, or oozing skin. Long-term venous pressure can also cause brown staining, hardened tissue, or a leg ulcer. The condition can be managed, but follow-up may also need to address the underlying vein circulation.

Who may develop venous eczema

Venous eczema is more common in middle-aged and older adults because vein function and mobility can change over time. It is often associated with visible varicose veins, swelling that is worse after standing, or a past blood clot in the leg. Prior cellulitis or a healed venous ulcer can also be part of the history.

Other factors can increase pressure in leg veins or make swelling more likely, including pregnancy, higher body weight, a family history of venous problems, limited mobility, and prolonged sitting or standing. These are risk factors, not proof that any one person has stasis dermatitis. The clinician also considers heart and kidney conditions, medicines, and other causes of leg swelling.

Stasis dermatitis can be mistaken for other skin problems, and some people have more than one condition at a time. A rash under a dressing or around a topical product may indicate contact allergy. Redness can also come from cellulitis, a blood clot, arterial disease, or another type of eczema. Accurate assessment helps avoid treating the wrong problem.

Common symptoms and skin changes

Early symptoms may include itch, dryness, scaling, soreness, or a patch of discolored skin around the inner ankle. The area can feel heavy or achy after standing or walking. Swelling often increases toward the end of the day and may be better after resting with the legs raised. Varicose veins can be visible, but they are not present in every case.

Skin color varies across skin tones and across stages of the condition. On lighter skin, active inflammation may look red, pink, or brown. On darker skin, it may appear dark brown, purple, grey, or as a change in texture rather than a bright red rash. Brown staining can persist after the active itch and inflammation settle, so color alone cannot show whether disease is currently active.

More established disease can cause dry cracks, small blisters, weeping, crusts, or thick scale. The skin may feel firm or tight. Some people develop lipodermatosclerosis, in which tissue becomes hardened and the lower leg narrows near the ankle. Small pale scars surrounded by reddish spots, called atrophie blanche, may occur. A wound may appear after even minor trauma when the skin is fragile.

What happens beneath the skin

Venous pressure explains why eczema tends to appear on the lower legs. When the leg is dependent for a long period, gravity increases the pressure in the veins. If valves are not functioning well, blood and fluid can pool rather than moving back toward the heart efficiently. Local inflammation and leakage of small amounts of blood pigment into the skin contribute to swelling and brownish discoloration.

Movement of the calf muscles helps pump blood through the veins. Walking, ankle flexion, and changing position can support that pump. Long periods of sitting or standing still can make swelling worse for some people. Leg elevation may reduce dependent swelling, but it should be comfortable and appropriate for the person's overall health. Ask a clinician if there is heart failure, shortness of breath when lying flat, or another condition that affects safe positioning.

Stasis dermatitis is not caused by poor hygiene, and it is not contagious. Scratching or rubbing can damage the skin and add irritation. The underlying circulation issue usually needs attention along with the rash; moisturizer alone may help dryness but will not correct venous pressure or treat an ulcer.

Possible complications

Fragile or inflamed skin can split, bleed, or become infected. Yellow crusts may suggest a superficial infection. Cellulitis can cause rapidly spreading redness, warmth, swelling, pain, fever, or a red streak; it requires medical assessment and sometimes antibiotic treatment. A clinician should examine a new wound, especially if it is slow to heal or has drainage.

Long-standing venous pressure can contribute to a venous leg ulcer, often near the ankle. An ulcer is a break in the skin that may take weeks or longer to heal. Wounds need an assessment of circulation, wound care, and usually a plan for managing venous pressure. Do not apply strong compression or an unprescribed dressing over an ulcer without guidance.

Repeated inflammation and scratching can lead to contact allergy from creams, ointments, bandages, or dressings. If a rash worsens after applying a product or spreads to a new area, tell the clinician. Patch testing may be considered if allergic contact dermatitis is suspected. Avoid repeatedly adding new products while the cause is uncertain.

How clinicians make a diagnosis

A clinician usually diagnoses stasis dermatitis by looking at the skin and considering the history of swelling, varicose veins, previous clots, leg ulcers, pain, itch, and the timing of symptoms. They may examine both legs, the ankles and feet, skin temperature and texture, wounds, pulses, and the pattern of discoloration. A history of heart disease or previous leg surgery may affect the plan.

Testing is not required for every typical case. A Doppler ultrasound may be used to assess vein blood flow, look for valve problems, or check for a clot when symptoms or examination raise that concern. Patch testing may be offered if an allergy to skin products or dressings is suspected. The clinician may request other tests if there is another possible cause of swelling or inflammation.

Because compression can be unsafe when arterial blood flow is reduced, clinicians may check pulses or measure the ankle-brachial pressure index, which compares blood pressure at the ankle with the arm. The test can help identify peripheral arterial disease and guide whether compression is suitable and how strong it can be. In diabetes or certain other conditions, the clinician may need additional assessment because a single measurement may not answer every question.

Cellulitis, contact dermatitis, nummular eczema, lipodermatosclerosis, arterial skin disease, and deep vein thrombosis can resemble or coexist with stasis dermatitis. New one-sided swelling or pain should not automatically be attributed to chronic eczema. The care team may involve a dermatologist, vascular specialist, primary care clinician, or wound-care nurse depending on findings.

Treatment: calm the skin and manage venous pressure

Treatment usually combines skin care with a plan to address swelling and venous circulation. The details depend on the person's skin, arterial blood flow, other medical conditions, activity level, and whether there is an ulcer. The aim is to relieve itch and inflammation, protect the skin barrier, reduce swelling where possible, and lower the chance of wounds or infection.

A regular emollient can reduce dryness and protect the skin. Use a bland, fragrance-free product recommended by a clinician or pharmacist, and apply it gently rather than rubbing vigorously. A mild, non-soap cleanser is often less irritating than fragranced soap. Thick ointments can be helpful for very dry skin, while creams may feel lighter. If an emollient contains paraffin or other oils, keep it away from flames and cigarettes because residue on clothing or bedding can increase fire risk.

For an active flare, a clinician may prescribe a topical corticosteroid for a limited period. The strength and duration depend on the affected site and severity. Use it only where instructed and do not continue or repeat it indefinitely without review; prolonged or inappropriate use can thin fragile skin. If symptoms do not improve, worsen, or return quickly, ask for reassessment instead of increasing the strength yourself.

Compression stockings, wraps, or bandaging can help some people by reducing venous pressure and swelling. The right type and pressure should be selected after assessment of arterial circulation and leg size. A trained clinician may measure the leg and show how to put the garment on without injuring fragile skin. Do not start strong compression on your own if circulation has not been assessed, especially with foot pain, cold toes, known arterial disease, diabetes-related nerve loss, heart failure, or an open wound.

Some people benefit from keeping active, taking short walks, flexing the ankles during long periods of sitting, and raising the legs while resting. A clinician can tailor this advice for mobility, balance, heart disease, and other conditions. If varicose veins are contributing to repeated symptoms or ulcers, a vascular specialist may discuss procedures to treat the vein problem. Antibiotics are used for a bacterial infection, not for stasis dermatitis itself.

Daily care to protect the lower legs

Check the lower legs and feet regularly for new cracks, blisters, wounds, drainage, or increased swelling. Use a mirror or ask for help if it is difficult to see the ankles and soles. Treat small injuries gently and contact a clinician if the skin opens, becomes more painful, or does not begin to heal.

Try to avoid scratching and friction from rough socks or tight footwear. Pat the skin dry after bathing, then apply moisturizer while the skin is still slightly damp. A fragrance-free cleanser can help avoid irritation. If a dressing or moisturizer seems to trigger a rash, pause new products and ask the clinician what to use instead.

Move the ankles during long sitting periods and take breaks from standing still when possible. Walking can engage the calf muscles, but activity should fit the person's mobility and medical advice. Elevate the legs when resting if it is comfortable and approved for their health conditions. These measures can support circulation and reduce swelling, but they do not replace treatment for venous disease or a wound.

Keep the prescribed skin and compression plan easy to follow. If stockings are too tight, roll down, cause pain, or are difficult to put on, contact the clinician or fitter. A poor fit can injure skin or create a tight band. Ask about donning aids, alternative garments, or help from a caregiver rather than cutting or altering the product yourself.

Differentiating a flare from something urgent

Stasis dermatitis often develops gradually and may persist or recur around the ankles. Cellulitis is more likely when redness, warmth, pain, and swelling worsen rapidly, especially with fever, chills, feeling unwell, pus, or a red streak. The conditions can coexist, so a new painful flare should be assessed rather than assumed to be eczema.

A deep vein thrombosis can cause new one-sided leg swelling, pain or tenderness, warmth, or a change in color. These symptoms need urgent medical assessment, particularly if they are sudden or unexplained. Chest pain, sudden breathlessness, fainting, or coughing blood can signal a clot-related emergency; call local emergency services.

Seek prompt care for a new ulcer, a wound that is worsening or not healing, blackened skin, severe pain at rest, a cold or pale foot, or rapidly increasing swelling. If a person with chronic heart disease develops swelling with new breathlessness, contact their medical team promptly. These problems may reflect circulation or infection issues beyond a skin flare.

Ongoing management and outlook

Stasis dermatitis often behaves as a chronic or recurring condition because the underlying venous pressure may continue. The skin can improve with a coordinated plan, yet flares may return after prolonged standing, swelling, irritation, or interruption of care. Brown staining may remain even when the eczema is quieter. Hardening and ulcers can be more difficult to reverse once established.

Follow-up can help confirm the diagnosis, check whether the skin treatment is working, assess compression fit, and look for venous disease or an ulcer. The plan may change if there are signs of arterial disease, heart failure, infection, contact allergy, or poor healing. Tell the clinician if a product stings, a stocking causes pain, or the rash spreads despite following the plan.

People who have an ulcer or severe venous disease may need long-term compression and vascular follow-up after a wound heals. Consistent emollient use, movement, safe elevation, and early attention to skin breaks can reduce avoidable damage. A written plan helps caregivers and other clinicians understand which symptoms are expected and which need prompt review.

Questions to ask your clinician

Ask whether the skin changes fit stasis dermatitis, whether venous insufficiency or another condition may be contributing, and whether circulation testing is needed before compression. Ask what type of moisturizer or prescription treatment to use, where to apply it, and when to stop or return for review.

If compression is recommended, ask how much pressure is appropriate, who will measure the leg, how to put the garment on safely, and what symptoms mean it should be removed or checked. If there is an ulcer, ask who will manage dressings and how often it should be reviewed.

Ask when to seek urgent care for infection, a possible blood clot, or an arterial circulation problem. If you have heart disease, diabetes, reduced sensation, or difficulty walking, ask how those conditions change the skin-care plan. Clear instructions can prevent self-treatment from becoming unsafe.

Key takeaways

Stasis dermatitis, or venous eczema, is lower-leg inflammation associated with venous insufficiency and swelling. It can cause itching, scale, brown discoloration, crusting, hardening, and sometimes ulcers. Diagnosis is usually clinical, with ultrasound, blood-flow testing, or patch testing selected when needed. Treatment may combine gentle skin care, a prescribed topical steroid for flares, activity or elevation, and properly assessed compression. Sudden leg swelling, spreading painful redness, fever, an open wound, or chest symptoms need prompt medical attention.
