Dermatitis

Dermatitis and eczema are terms that denote an inflammatory reaction involving the epidermis and dermis, and are used interchangeably. There are many forms of dermatitis.

• Atopic dermatitis–The result of a complex interaction between genetic and environmental factors. Usually manifests as dry, itchy skin. Poorly defined erythematous patches, papules, and plaques, sometimes with scale.
• Allergic contact dermatitis–Caused by an antigen that triggers a type IV (cell-mediated) hypersensitivity reaction.It usually manifests as erythema and edema with superimposed papules or vesicles that are sharply demarcated, corresponding to the areas of exposure.
• Irritant contact dermatitis–Caused by a chemical irritant, usually occurring minutes or up to 24 hours after exposure. It usually manifests as erythema and/or vesiculation that are sharply demarcated, corresponding to the areas of exposure.
• Stasis dermatitis-Chronic venous insufficiency occurs when dysfunction of the venous system of the lower extremitiesleads to venous hypertension. This process most commonly develops as a result of venous valvular incompetence related to previous clinical or occult DVTs. Clinical sequelae include pain, edema, and skin changes such as telangiectasias, varicosities, hemosiderosis-related hyperpigmentation, lipodermatosclerosis (a fibrotic process involving the dermis and subcutaneous fat), and ulcerations (typically near the medial malleoli).
