Venous (varicose, stasis) eczema is a chronic inflammatory skin condition that most commonly develops on the lower legs as a result of varicose veins and chronic venous insufficiency. It typically appears as areas of redness or darkening of the skin accompanied by scaling, swelling, and itching. Over time, the skin may become thickened, dry, and develop a brownish discoloration.
Itching associated with venous eczema is often persistent or recurrent. Many patients notice that symptoms worsen in the evening, after prolonged standing, during hot weather, or following a hot shower. In addition to itching, people may experience a feeling of heaviness in the legs, burning sensations, and skin tenderness.
The condition is not contagious and cannot be transmitted to other people. Venous eczema is a common complication of chronic venous disease and is particularly common in people over the age of 45. With timely treatment, symptoms can usually be effectively controlled.
What to Do If You Suspect Venous Eczema
If itchy areas of redness, scaling, or skin discoloration appear on the lower legs, especially in the presence of varicose veins, it is recommended to consult a dermatologist or a vascular specialist.
Because the condition is related not only to the skin but also to impaired venous circulation, it is important to evaluate the condition of the veins in the lower extremities. A doctor may order additional tests to assess for chronic venous insufficiency.
Before consulting a specialist, it is advisable to avoid scratching the skin, injuring the affected areas, and using potent medicated creams without medical supervision.
Evaluation should not be delayed. Without treatment, the condition may progress, and in severe cases the risk of developing venous leg ulcers increases.
What Venous Eczema Looks Like
In most cases, skin changes appear on the inner ankles and the lower third of the legs.
Typical signs of the condition include:
- redness of the skin;
- brown, reddish-brown, or dark red patches;
- scaling;
- dry skin;
- swelling of the lower legs;
- small blisters;
- weeping areas;
- scratch marks and crusts;
- thickening of the skin in long-standing disease.
In the early stages, symptoms may be subtle. Sometimes the first sign is only itching or the appearance of small dark spots around the ankles.
As the condition progresses, the skin becomes thicker, changes color, and may lose elasticity.
Below in the article, you can see real photos to better understand what the condition looks like.
It is important to remember that the appearance of venous eczema can vary significantly depending on the stage of the disease and the severity of venous circulation problems.
Main Symptoms
The most characteristic symptom is itching of the lower legs.
Other common symptoms include:
- scaling;
- dry skin;
- redness;
- skin darkening;
- a feeling of heaviness in the legs;
- swelling that worsens in the evening;
- burning sensations;
- skin tenderness;
- development of weeping areas;
- formation of crusts.
Many patients notice that symptoms improve after resting with the legs elevated and worsen after prolonged standing or sitting.
Causes of the Condition
The primary cause of venous eczema is chronic venous insufficiency.
Under normal conditions, blood in the veins should efficiently return from the legs to the heart. When the venous valves do not function properly, some blood begins to pool in the lower extremities.
Risk factors include:
- varicose veins;
- chronic venous insufficiency;
- a history of deep vein thrombosis;
- excess body weight;
- a sedentary lifestyle;
- prolonged standing or sitting at work;
- age-related vascular changes.
As blood stagnates, pressure inside the veins increases, gradually damaging surrounding tissues and leading to skin inflammation.
How Venous Eczema Develops
In chronic venous insufficiency, blood accumulates in the veins of the lower limbs.
Over time, the fluid portion of the blood begins to leak through the vessel walls into surrounding tissues. This leads to swelling and chronic inflammation.
The skin receives less oxygen and fewer nutrients. As a result, it becomes more sensitive, drier, and more prone to damage.
Against this background, itching, scaling, discoloration, and the characteristic signs of eczema develop. In long-standing cases, venous leg ulcers may form.
Forms and Types
Venous eczema can vary in severity.
Mild Form
Primarily characterized by dry skin, itching, and small areas of redness.
Moderate Form
Associated with pronounced scaling, persistent skin discoloration, and swelling.
Severe Form
May involve weeping skin, skin thickening, chronic inflammation, and the development of venous leg ulcers.
Conditions That Can Be Mistaken for Venous Eczema
Venous eczema is often mistaken for other skin disorders, particularly in its early stages.
Venous Eczema or Psoriasis?
Psoriasis usually presents as thick plaques covered with silvery scales and most commonly affects the elbows, knees, and scalp.
Venous eczema primarily develops on the lower legs and is accompanied by signs of venous circulation problems such as swelling, heaviness in the legs, and skin discoloration.
Venous Eczema or a Fungal Infection?
Fungal infections can cause itching and scaling, but they typically have more clearly defined borders and characteristic peripheral spread.
Venous eczema is usually associated with varicose vein disease and occurs around the ankles and lower legs.
Venous Eczema or Lichen?
Some forms of lichen may also cause redness and scaling of the skin.
However, venous eczema is almost always accompanied by signs of chronic venous insufficiency.
Venous Eczema or Scabies?
Scabies is characterized by intense nighttime itching and the presence of burrows.
With venous eczema, itching is usually accompanied by swelling, skin darkening, and symptoms of varicose vein disease.
Venous Eczema or Cellulitis (Bacterial Skin Infection)?
In bacterial skin infections, redness usually develops rapidly, is often painful, and may be accompanied by fever.
Venous eczema develops gradually and follows a chronic course.
When to See a Doctor
A specialist consultation is recommended if:
- persistent itching develops on the lower legs;
- the skin begins to darken or thicken;
- leg swelling occurs regularly;
- weeping areas appear;
- painful cracks develop;
- varicose veins are present;
- ulcers or slow-healing skin wounds appear.
It is especially important to seek evaluation when skin symptoms occur together with significant varicose veins.
Treatment
Treatment of venous eczema focuses on both reducing skin inflammation and correcting venous circulation problems.
Proper skin care plays an important role. Regular use of moisturizers is recommended to reduce dryness and restore the skin barrier.
It is also important to address factors that contribute to venous congestion.
A doctor may prescribe topical treatment in the form of creams or ointments to reduce inflammation and itching.
In people with chronic venous insufficiency, additional therapies aimed at improving venous blood flow may be recommended.
In cases of significant varicose veins, specialized treatment of the underlying venous disease may be necessary.
The treatment plan is always individualized after a thorough medical evaluation.
Questions and Answers
Can venous eczema be cured?
In many cases, symptoms can be significantly reduced or completely controlled. However, long-term improvement usually requires treating both the skin condition and the underlying venous disease.
Is venous eczema dangerous?
The eczema itself is usually not life-threatening. However, without treatment, the condition may progress and lead to chronic leg ulcers.
Will the eczema disappear after varicose vein treatment?
In many patients, skin symptoms improve significantly after correction of venous circulation problems. However, additional dermatologic treatment may still be necessary.
Are venous eczema and varicose veins the same thing?
No. Varicose veins are a disease of the veins, while venous eczema is a complication that develops as a result of impaired venous circulation.
Why does the skin become brown?
Because of prolonged venous congestion, some blood components leak from the vessels and accumulate in the skin, causing brown discoloration.
Can venous eczema occur without visible varicose veins?
Yes. In some cases, the condition develops in people with chronic venous insufficiency even without obvious external signs of varicose veins.
Can the affected skin get wet?
Normal hygiene is acceptable, but hot water may worsen itching and skin dryness.
Do venous leg ulcers always develop?
No. With timely treatment, most patients do not experience this complication.
