title: [Allergic delayed reactions of the skin: the role of the antigen histotopy].
abstract: Delayed skin reaction to tuberculin were elicited in 10 healthy persons by patch testing and intracutaneous application of the antigen (Tine-Test). Biopsies revealed basically identical tissue reactions. After intracutaneous injection of the antigen as well as after Tine-testing the changes were solely found in the dermis, while after patch testing dermal and epidermal alterations were prominent. The type of response elicited by the same allergen in man-the so called tuberculin type of the eczematous type-therefore are due to a differential localization of the antigen.
