Sites of contact dermatitis in relationship to particular allergens.

A study of 1016 patients over a period of 2 years has been performed by using the DALUK computer system in order to find correlations between eczema sites and particular allergens. The study includes a control material of patients with other contact allergies or with negative patch tests. The investigation confirms some well-known correlations, e.g., between lanolin allergy and dermatitis of the lower leg, and between nickel allergy and dermatitis of the palm. Several new correlations are also described, e.g., chromium allergy and dermatitis of the back of the trunk, allergy to balsam of Peru and dermatitis of the forehead and cheek.
