Topic Resources

Stasis dermatitis is inflammation, typically of the skin of the lower legs, caused by chronic edema. Symptoms are itching, scaling, and hyperpigmentation. Ulceration can be a complication. Diagnosis is clinical. Treatment is directed at the causes of edema and preventing ulceration.

Stasis dermatitis occurs in patients with chronic edema due to, for example, chronic venous insufficiency, right heart failure, or lymphedema. 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.

Stasis dermatitis as well as chronic venous insufficiency and leg ulcers, which commonly accompany stasis dermatitis, are sometimes treated with various topical drugs. Thus, contact dermatitis often complicates stasis dermatitis (1).

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, also called sclerosing panniculitis), giving the lower leg an inverted bowling pin shape with enlargement of the calf and narrowing at the ankle.

Manifestations of Stasis Dermatitis

Diagnosis of Stasis Dermatitis

  • Clinical evaluation

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. Chronic venous insufficiency 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). 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. Topical antibiotics (eg, mupirocin, silver sulfadiazine) are useful for treating erosions and ulcers. 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).

Key Points

  • 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.
