id

 [id]
a freudian term used to describe that part of the personality which harbors the unconscious, instinctive impulses that lead to immediate gratification of primitive needs such as hunger, the need for air, the need to move about and relieve body tension, and the need to eliminate. Id impulses are physiologic and body processes, as opposed to the ego and superego, which are psychologic and social processes. The id is dominated by the pleasure principle and some gratification of the id impulses is necessary for survival of a person's personality.
id reaction a localized or generalized, sterile secondary skin eruption occurring in sensitized patients as a result of circulation of allergenic products from a primary site of infection; the morphology and site of the lesion vary.

id re·ac·tion

an allergic manifestation of candidiasis, the dermatophytoses, and other mycoses characterized by itching, vesicular lesions that appear in response to superficial infections that are distant from the id reaction itself.

id reaction

the autosensitization resulting from any inflammatory condition that causes pruritus and vesicular lesions. These secondary lesions are caused by circulating antigens and are usually distant from the primary infection.

id reaction

Dermatophytid reaction Dermatology A localized or generalized rash of sudden onset associated with, but located at a distance from, a site of cutaneous inflammation and/or infection; IRs occur on the hands and arms, as sterile papulovesicular pustules, classically associated with dermatophytosis–eg, tinea pedis, tinea capitis and may be associated with stasis dermatitis, eczema and contact dermatitis, which disappear after successful therapy; because the IR is similar to the original lesion, it is thought to represent an immune to circulating antigens. Cf Id, Isomorphic phenomenon.
