Increased capillary pressure with subsequent compromise of endothelial integrity in the microvasculature results in fibrin leakage, and disruption of the epithelial barrier function results in local inflammation. Stasis dermatitis occurs most commonly on the shins but can also affect other areas with chronic edema, such as the arms after radiation treatment of axillary lymph nodes.

Symptoms and Signs of Stasis Dermatitis
Manifestations typical of stasis dermatitis include pruritus, ill-defined erythema, scaling, and lichenification, most commonly on the shins. There are also plaques, often weeping and crusted, commonly with bacterial superinfection.
When chronic venous insufficiency is the cause, other manifestations usually include varicose veins, purpura jaune d'ocre (a yellow-brown discoloration due hemosiderin deposits in the dermis), and lipodermatosclerosis (sclerosis of subcutaneous fat caused by panniculitis Panniculitis Panniculitis describes inflammation of the subcutaneous fat that can result from multiple causes. Diagnosis is by clinical evaluation and biopsy. Treatment depends on the cause.

Diagnosis of Stasis Dermatitis
Diagnosis of stasis dermatitis is clinical based on the characteristic appearance of the skin lesions and other signs of chronic leg swelling and venous insufficiency. Consultation with a vascular specialist and testing (such as Doppler ultrasonography) may be needed.
Treatment of Stasis Dermatitis
Treatment of the causes of swelling
Compression and elevation
Treatment of complications (eg, secondary infection, allergic contact dermatitis, ulcers)
The cause of the chronic swelling should be corrected to the extent possible. Leg elevation and compression are often indicated.

Postphlebitic (postthrombotic) syndrome is symptomatic chronic... read more should be treated.
In addition, noneroded stasis dermatitis often abates with a midpotency topical corticosteroid (eg, triamcinolone acetonide 0.1% cream or ointment). For an eroded (weeping) lesion, a hydrocolloid dressing may be best.
Ulcers are best treated with compresses and bland dressings (eg, zinc oxide paste); other dressings (eg, hydrocolloids) are also effective ( see also Direct wound care Direct wound care ). Ulcers in ambulatory patients may be healed with an Unna paste boot (zinc gelatin), a less messy zinc gelatin bandage, or a colloid dressing (all are available commercially). Colloid-type dressings used under elastic support are more effective than an Unna paste boot. It may be necessary to change the dressing every 2 or 3 days, but as edema recedes and the ulcer heals, once or twice/week is sufficient. After the ulcer heals, an elastic support should be applied before the patient rises in the morning. Regardless of the dressing used, reduction of edema (usually with compression) is paramount for healing.
Oral antibiotics (eg, cephalosporins, dicloxacillin) are used to treat superimposed cellulitis Cellulitis Cellulitis is acute bacterial infection of the skin and subcutaneous tissue most often caused by streptococci or staphylococci.

When edema and inflammation subside, split-thickness skin grafts may be needed for large ulcers.
Complex or multiple topical drugs or over-the-counter remedies should not be used. The skin in stasis dermatitis is more vulnerable to direct irritants and to potentially sensitizing topical agents (eg, antibiotics; anesthetics; vehicles of topical drugs, especially lanolin or wool alcohols).
Stasis dermatitis results from chronic edema, most typically on the shins.
Signs include erythema, scaling, pruritus, and lichenification and may include weeping erosions and crusting.
Complications include secondary infections, ulcers, and contact sensitivities.
Elevation and compression are often required.
