Venous and gravitational eczema

01OverviewDefinition, clinical context and the essential points that orientate the chapter.

Look from toes to groin. Record oedema, varicosities, haemosiderin, atrophie blanche, lipodermatosclerosis, ulcers, pulses and temperature. In deeply pigmented skin, active inflammation may appear darker, purple or grey and be detected through warmth, itch, scale and ooze; chronic haemosiderin is brown and persists after inflammation settles.

Management integrates dermatology and vascular care. Emollient and topical corticosteroid settle skin, but venous pressure requires movement, leg elevation and suitable compression. NICE referral supports duplex assessment and definitive treatment options for venous skin changes. A painful or infected ulcer needs a separate wound and vascular pathway.

Venous and gravitational eczema care should combine visible inflammation with itch, pain, sleep, occupation and treatment burden. Agree where each product goes, how much is used and when response will be reviewed; explain urgent features separately so normal fluctuation is not confused with infection or treatment failure.

Key points

Venous eczema affects the lower gaiter region with itch, scale, oedema, haemosiderin colour, varicosities and sometimes lipodermatosclerosis or ulceration.
Bilateral chronic itch and scale favour venous inflammation; acute unilateral pain, fever or rapid spread requires assessment for cellulitis or thrombosis.
Check arterial symptoms and pulses and obtain the locally required vascular assessment before compression; do not prescribe compression blindly.
NICE recommends vascular-service referral for lower-limb skin changes such as pigmentation or eczema thought caused by chronic venous insufficiency.
Treat active eczema with daily emollient, soap substitution and a site-appropriate topical corticosteroid while addressing oedema and mobility.
Compression is a long-term venous treatment when arterial supply and contraindications have been assessed, not merely a dressing for the rash.
For Venous and gravitational eczema, document body sites, severity, sleep and function, recent treatment, infection features and what the patient can realistically apply each day.
In Venous and gravitational eczema, reassess the diagnosis when a well-used, correctly potent regimen fails rather than repeatedly intensifying treatment without examining adherence, exposure and mimics.

02AetiologyUnderlying causes, associations and risk factors, with why each one matters.

Venous valve failure

Primary varicosities, previous thrombosis and calf-pump impairment cause reflux and sustained ambulatory venous hypertension in the lower leg.

Oedema and immobility

Reduced walking, obesity, prolonged standing or sitting and dependent sleep impair calf-pump return and increase fluid accumulation.

Skin exposure and sensitisation

Chronic exudate, dressings, adhesives, topical antibiotics and preservatives can add irritant or allergic dermatitis to the venous inflammatory background.

03PathophysiologyThe causal sequence from the underlying abnormality to symptoms and harm.

1
Microvascular hypertension
Raised venous pressure distends capillaries and promotes fluid, erythrocyte and protein leakage into tissue, generating oedema and inflammation.
2
Haemosiderin deposition
Extravasated erythrocytes break down and leave iron-containing pigment, producing persistent brown lower-leg colour that does not indicate active eczema alone.
3
Fibrosing inflammation
Chronic cytokine and subcutaneous fat inflammation hardens the gaiter area as lipodermatosclerosis and reduces local tissue resilience.
4
Barrier breakdown
Oedema, itch and scratching disrupt epidermis, causing weeping eczema and increasing risk of ulceration and bacterial entry.

04Clinical features and red flagsSymptoms, examination findings, patterns of presentation and time-critical warnings.

Gaiter-zone dermatitis

Itchy scaly or weeping inflammation clusters above the medial ankles with dependent oedema and varicose veins.

Chronic venous markers

Brown haemosiderin, white atrophic scars, ankle flare and indurated inverted-bottle legs support long-standing hypertension.

Bilateral inflammatory pattern

Both lower legs may be warm, itchy and inflamed without systemic illness, often mistaken for bilateral cellulitis.

Ulcer and contact pattern

An irregular gaiter ulcer plus sharply geometric dermatitis under adhesive or topical treatment suggests concurrent contact allergy.

Acute vascular departureRed flag

Sudden one-sided swelling, calf pain, cold foot, rest pain, absent pulse or chest symptoms needs urgent assessment.

Red flags requiring action

Sudden unilateral swelling, chest symptoms, rest pain, cold foot, absent pulses, fever, rapidly increasing erythema, severe ulcer pain or uncontrolled bleeding requires urgent vascular or medical assessment.

05InvestigationsWhat to request, why it matters and how to interpret it.

Investigation order

Read from the initial assessment onwards. Tests may run in parallel in urgent care; first-line, preferred, confirmatory, definitive and gold-standard labels appear only when the chapter explicitly states them.

01
Pulse and limb vascular examinationFirst step
Why
Identify arterial compromise or acute vascular threat before compression.
Interpretation and limitations
Palpable pulses are reassuring but may not be sufficient in diabetes, calcification or ulceration; follow local vascular-testing pathways.
02
Ankle-brachial pressure or alternative assessment
Why
Quantify arterial supply when compression is considered.
Interpretation and limitations
Interpret cautiously in diabetes, renal disease and calcified vessels where readings may be falsely high and toe pressure or specialist assessment is needed.
03
Venous duplex through a vascular service
Why
Confirm reflux or obstruction and plan intervention.
Interpretation and limitations
NICE recommends duplex in a vascular service for suspected varicose-vein disease; eczema appearance alone cannot map treatable reflux.
04
Ulcer measurement and infection assessment
Why
Document wound trajectory and identify cellulitis or other complications.
Interpretation and limitations
Size, depth, exudate and pain are more useful than routine surface swabs; culture only when infection and treatment decisions warrant it.
05
Patch testing for treatment-resistant dermatitis
Why
Identify allergy to dressings, adhesives, preservatives or topical antibiotics.
Interpretation and limitations
Test actual products and relevant series; positive sensitisation needs exposure relevance before changing wound materials.

06Differential diagnosisRealistic alternatives and the features that help distinguish them.

Cellulitis

Acute progressive unilateral warmth, tenderness, swelling and systemic illness differs from usually bilateral chronic itchy venous inflammation, although infection can complicate eczema.

Allergic contact dermatitis

Sharp worsening beneath dressings or after topical products, especially spreading beyond the ulcer area, supports sensitisation and patch-test referral.

Arterial disease

Rest pain, cool pale foot, tissue loss, reduced pulses and abnormal pressure assessment indicate impaired arterial supply and alter compression safety.

Deep-vein thrombosis

Sudden unilateral swelling and pain with thrombosis risk requires urgent diagnostic assessment rather than routine eczema treatment.

07ManagementImmediate care, first-line treatment, alternatives and escalation.

01Stable venous eczemaTreat skin and dependent pressureFirst stepChronic gaiter eczema and oedema occur without acute arterial, thrombotic or infectious red flags.

1Use leave-on emollient daily as cleanser and moisturiser and a defined course of topical corticosteroid only on actively inflamed patches.
2Encourage walking, calf activation and periods of leg elevation while reducing prolonged dependent sitting or standing where feasible.
3Assess arterial supply, then introduce correctly fitted compression through the appropriate trained service and review tolerance.

02Vascular referralDefine and treat venous refluxPigmentation, eczema, lipodermatosclerosis, symptomatic varicosities or a venous ulcer suggests chronic venous insufficiency.

1Refer to a vascular service in line with NICE CG168 and supply ulcer history, pulses, previous thrombosis and mobility information.
2DefinitiveUse duplex ultrasound to confirm reflux and plan intervention rather than regarding stockings as the only definitive option.
3Continue compression and skin care when safe while coordinating weight, mobility and wound management.

03Acute deteriorationSeparate cellulitis, thrombosis and ischaemiaRapid unilateral pain or swelling, fever, lymphangitis, cold foot, rest pain or chest symptoms appear.

1Arrange same-day emergency assessment with observations and limb neurovascular examination; use the thrombosis, sepsis or ischaemia pathway indicated.
2Do not increase compression over an acutely ischaemic, unassessed or severely painful limb.
3After the emergency is resolved, revisit venous control, ulcer prevention and any contact allergy created by acute dressings.

Key medicines and prescribing safety1 treatment · regimens, roles and cautions

A potent topical corticosteroid for inflammatory venous eczema alongside emollient, oedema control and vascular management.

Betamethasone valerate 0.1% cream

Apply thinly to active intact lower-leg eczema once or twice daily for up to four weeks, then reduce or stop when inflammation is controlled.

Avoid ulcer beds, untreated infection, large denuded areas and unplanned occlusion; review atrophy and contact sensitivity and do not mistake haemosiderin pigment for active disease.

08ComplicationsImportant consequences, why they occur and why they matter clinically.

Venous ulceration

Progressive inflammation, oedema and minor trauma can produce chronic gaiter-region ulcers with pain, exudate, infection risk and major care burden.

Lipodermatosclerosis

Fibrotic inverted-bottle contour and painful inflammatory panniculitis reduce mobility and may be mistaken for recurrent bacterial cellulitis.

Secondary infection

Barrier loss can lead to cellulitis, lymphangitis or systemic infection, particularly when oedema and ulcers remain uncontrolled.

Contact sensitisation

Repeated exposure to dressings and topical agents makes lower-leg patients vulnerable to allergy that perpetuates apparently treatment-resistant eczema.

09Monitoring and follow-upTreatment response, safety checks and longer-term review.

Measure oedema, skin activity, ulcer dimensions, pain, mobility and compression tolerance at each venous-eczema review.
Check garment fit and condition, arterial symptoms and whether the patient can put on and remove compression safely.
Reassess persistent dermatitis for contact allergy, tinea and inadequate venous control rather than cycling topical antibiotics.
At review of Venous and gravitational eczema, compare itch, sleep, fissuring or ooze, affected sites, function and treatment use with the agreed baseline.
For Venous and gravitational eczema, record adverse effects, new contact exposures and the safety-net for pain, fever, rapidly spreading disease, eye symptoms or systemic illness.

10Special situationsVariants, exceptions and circumstances that change the usual approach.

Brown does not equal active

Haemosiderin pigment remains after eczema settles, so itch, scale, warmth and ooze are better markers of current inflammation.

Bilateral cellulitis is uncommon

Two chronically inflamed lower legs without systemic illness more often reflect venous eczema or lipodermatosclerosis.

Compression needs a circulation check

An appropriate arterial assessment and trained fitting protect patients whose lower-leg eczema coexists with arterial disease.

Skin change warrants referral

NICE includes pigmentation or eczema caused by chronic venous insufficiency among indications for vascular-service assessment.

Dressings can become allergens

Chronic ulcer care repeatedly exposes skin to adhesives, preservatives and topical antibiotics, making patch testing valuable in refractory cases.

11Common pitfallsFrequent interpretation and management errors.

01
Prescribing compression without assessing arterial symptoms, pulses and locally required haemodynamic testing.
02
Calling bilateral chronic itchy lower-leg inflammation cellulitis and giving repeated antibiotics.
03
Applying potent corticosteroid directly into a venous ulcer rather than to selected surrounding eczema.
04
Treating persistent brown haemosiderin as ongoing steroid-responsive inflammation.
05
Failing to refer venous skin changes for duplex and possible definitive intervention.
