[Allergic contact dermatitis due to tromantadin (author's transl)]

37 observations on allergic contact dermatitis due to tromantadine are reported. With the increasing distribution and application of this adamantane derivative, the incidence of this type of clinical picture will probably increase further. The attendant physician should therefore accordingly explain to his patients and inform them of the initial symptoms - presumably striking intensification and local extension of the herpes eruption in spite of intensive treatment.
