Stasis dermatitis: the leg eczema caused by poor vein circulation
Last updated September 3, 2026.
Stasis dermatitis (the varicose eczema) is the lower-leg skin inflammation caused by the failing leg veins: the itchy, red-or-brown, scaly skin around the ankles and the shins, with the swelling and the brown staining (the hemosiderin: the leaked blood-pigment settling in the skin). It signals the underlying venous insufficiency (the same problem behind the varicose veins), it matters because the untreated skin breaks down into the leg ulcers, and the compression stockings plus the skin care are the foundation of the treatment.
What does it look like?
The lower-leg pattern, often the both legs but the one worse: the itching and the scaling around the ankles-and-shins, the reddish-or-brownish discoloration (the brown staining that persists), the ankle swelling (the worse-by-evening, better-by-morning kind), the heaviness-and-aching of the legs, sometimes the varicose veins alongside, and the flares of the weeping-or-crusted eczema. The late-stage skin turns the hard-and-tight (the lipodermatosclerosis) and the ulcers form at the ankles: the stage to prevent.
Why does it happen?
The vein valves failing: the leg veins rely on the one-way valves and the calf-pump to return the blood upward; the valves fail (the age, the previous clots, the varicose-vein tendency, the obesity, the prolonged standing), the pressure builds in the lower-leg veins, the fluid and the blood-pigments leak into the skin, and the inflammation follows. The risks: the age, the previous deep-vein thrombosis, the obesity, the pregnancies, the family history, and the standing occupations.
What actually helps?
- The compression stockings: the foundation: the graduated compression pushing the blood upward (the properly-fitted kind, worn daily, put on before the swelling of the day).
- The skin care: the daily emollient (the barrier repair), the steroid cream for the flares (the short courses on the inflamed patches), the gentle washing.
- The leg elevation and the movement: the legs raised above the heart when resting, the calf-pump exercises (the ankle circles, the walking), the prolonged standing-or-sitting interrupted.
- The cause addressed: the vein assessment (the ultrasound of the veins), the weight management, the varicose-vein treatment when indicated.
When does it need the prompt care?
The prompt review for: the ulcer forming (the broken skin at the ankle that does not heal), the infection signs (the spreading redness, the heat, the pain, the fever: the cellulitis the legs are prone to), the one-leg sudden swelling-with-pain (the clot: the same-day), and the skin hardening-or-darkening rapidly. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
Why is my skin turning brown? Will it fade?
The brown is the hemosiderin: the red blood cells leaking out of the pressurized veins, the iron pigment settling in the skin (the rust-deposit, essentially). It fades little even with the good treatment (the pigment is stubborn), but the point of the treatment is not the color: it is stopping the progression (the inflammation, the hardening, the ulcers). The compression controls the leakage; the existing staining is the record of the years, not the sentence.
Do compression stockings really make a difference?
They are the single most effective measure, and the evidence is the strongest kind: the graduated compression directly counters the valve failure (pushing the blood upward, shrinking the swelling, reducing the leak into the skin), the skin improves measurably, and the ulcer prevention is the proven benefit. The fit matters (the measured-for, not the grabbed-off-the-shelf, for the medical grades), and the daily consistency matters more than the strength.
Is this related to my varicose veins?
The same underlying problem: the varicose veins and the stasis dermatitis are the two faces of the venous insufficiency (the failing valves), and treating the underlying veins (the modern vein procedures, when the ultrasound shows the treatable kind) can improve both. Ask for the vein assessment: the dermatitis managed without the vein evaluation is the half-plan.
My mother had leg ulcers. Is that my future?
Not automatically: the ulcers are the end-stage of the untreated venous insufficiency, and the difference between her trajectory and yours is largely the compression-and-skin-care started at your stage (the dermatitis stage: the warning, not the ulcer). The family tendency is real (the valve weakness runs in the families), which is all the more reason the stockings start now rather than at the first broken skin.
The stockings are miserable in summer. Alternatives?
The common complaint, with the honest options: the lighter compression classes exist (the lower-grade for the maintenance), the open-toe kinds breathe better, the wearing-them-in-the-coolest-part-of-the-day preserves some benefit, and the leg elevation-plus-movement partially substitutes on the unwearable days. The skin care continues regardless, and the winter adherence is the non-negotiable season.
What makes the itching stop?
The short steroid courses on the inflamed patches (the flare-control), the emollient as the daily barrier (the itch follows the barrier failure), the lukewarm-not-hot washing, the no-scratching discipline (the cold compress instead: the scratching opens the skin to the ulcers and the infection), and the compression treating the underlying driver. The persistent itch despite these deserves the review: the contact allergy to the creams themselves occasionally complicates this condition.
