Autoeczematization
Autoeczematization refers to the development of widespread dermatitis or dermatitis distant from a local inflammatory focus.James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. . Autosensitization (autoeczematization or "id" reaction) refers to an acute, pruritic papulovesicular eruption that develops at cutaneous sites distant from a primary focus and is unrelated to the inciting cause of the primary inflammation. The pathogenesis is not fully understood. One hypothesis is that autoeczematization is due to hyperirritability of the skin induced by immunologic or nonimmunologic stimuli and mediated by epidermal cytokines. Histologic findings are nonspecific and include spongiosis and a dermal lymphohistiocytic infiltrate with eosinophils.

Dermatitis
Dermatitis is inflammation of the skin, typically characterized by itchiness, redness and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. The area of skin involved can vary from small to covering the entire body. Dermatitis is often called eczema, and the difference between those terms is not standardized. The exact cause of the condition is often unclear. Cases may involve a combination of allergy and poor venous return. The type of dermatitis is generally determined by the person's history and the location of the rash. For example, irritant dermatitis often occurs on the hands of those who frequently get them wet. Allergic contact dermatitis occurs upon exposure to an allergen, causing a hypersensitivity reaction in the skin. Prevention of atopic dermatitis is typically with essential fatty acids, and may be treated with moisturizers and steroid creams. The steroid creams should generally be of mid ...

Autosensitization Dermatitis
Autosensitization dermatitis presents with the development of widespread dermatitis or dermatitis distant from a local inflammatory focus, a process referred to as autoeczematization. See also * Id reaction Id reactions (also known as "disseminated eczema," and "generalized eczema") are types of acute dermatitis developing after days or weeks at skin locations distant from the initial inflammatory or infectious site. They can be localised or generalis ... * List of cutaneous conditions References External links Eczema {{Cutaneous-condition-stub ...

List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm th ...
