Clinical Information

Dermatitis, Allergic Contact - A contact dermatitis due to allergic sensitization to various substances. These substances subsequently produce inflammatory reactions in the skin of those who have acquired hypersensitivity to them as a result of prior exposure.

Dermatitis, Atopic - A chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. It is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. In infants it is known as infantile eczema.

Dermatitis, Contact - A type of acute or chronic skin reaction in which sensitivity is manifested by reactivity to materials or substances coming in contact with the skin. It may involve allergic or non-allergic mechanisms.

Eczema - A dermatitis characterized by a spongiotic tissue reaction pattern occurring as a reaction to many endogenous and exogenous agents.

Eczema, Dyshidrotic - A recurrent eczematous reaction characterized by the development of vesicular eruptions on the palms and soles, particularly along the sides and between the digits. It is accompanied by pruritus, a burning sensation, and hyperhidrosis. The disease is self-limiting, lasting only a few weeks. (Dorland, 27th ed)
