Synopsis

Id reaction, also known as autoeczematization, secondary dermatitis, autosensitization dermatitis, and generalized eczema, occurs when eczema develops at sites not exposed to an inciting agent. It is usually observed with allergic or irritant contact dermatitis, severe bacterial or fungal infection, and, in adults, stasis dermatitis, but it is also seen in association with other forms of eczematous dermatitis. The reaction usually appears a few days to weeks after the primary dermatitis and can be severely pruritic. It shows a symmetric pattern and has a predilection for the palms, soles, and extensor surfaces of the upper extremities.

In children, id reaction is most often observed after a kerion, an acute inflammatory reaction that accompanies severe cases of tinea capitis. When associated with a kerion, the id reaction typically affects the upper body and face. Id reaction is also commonly observed in children in association with allergic contact dermatitis to nickel.

The condition is thought to result from a lower threshold for developing an eczematous hypersensitivity reaction in patients with preceding or concurrent inflammatory processes of the skin. In the case of tinea, it is often noted shortly after the institution of effective therapy and can be mistaken for an allergic reaction to the medication. All ages and skin types and both sexes are equally affected.
