Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents. [1] Symptoms of contact dermatitis can include itchy or dry skin, a red rash, bumps, blisters, or swelling. These rashes are not contagious or life-threatening, but can be very uncomfortable.
[1] [2] In the United States, it affects about 10–30% of people. [2] Contact dermatitis is twice as common in females as in males. [11] Allergic contact dermatitis affects about 7% of people at some point in their lives. [12] Irritant contact dermatitis is common, especially among people with certain occupations; exact rates are unclear. [13]
Allergic contact dermatitis (ACD) is a form of contact dermatitis that is the manifestation of an allergic response caused by contact with a substance; the other type being irritant contact dermatitis (ICD). Although less common than ICD, ACD is accepted to be the most prevalent form of immunotoxicity found in humans. [1]
Erythroderma is generalized exfoliative dermatitis, which involves 90% or more of the patient's skin. [3] The most common cause of erythroderma is exacerbation of an underlying skin disease, such as Harlequin-type ichthyosis, psoriasis, contact dermatitis, seborrheic dermatitis, lichen planus, pityriasis rubra pilaris or a drug reaction, such as the use of topical steroids. [4]
Stasis dermatitis, allergic contact dermatitis, acute irritant contact eczema and infective dermatitis have been documented as possible triggers, but the exact cause and mechanism is not fully understood. [7] Several other types of id reactions exist including erythema nodosum, erythema multiforme, Sweet's syndrome and urticaria. [3]
Low humidity from air conditioning was found to be the most common cause of physical irritant contact dermatitis. [3] To the lay person a definition of low humidity being a physical irritant can be confusing because low humidity is a deficit (or absence) of an elemental substance, whereas all other irritants implicated in contact dermatitis are in concentrations of relative abundance.
For cutaneous diseases, the diagnosis could be dry skin (with flare ups at dry climate), irritant and allergic contact dermatitis (skin lesions), seborrheic dermatitis (skin lesions), atopic dermatitis (scratching, allokinesis, stinging, burning), psoriasis (skin lesions), urticaria (welts/skin swelling).
