[Gaillardia allergy].
Allergic contact dermatitis of the face and hands occurring in a 37-year-old savings-bank employee was found to be due to non-occupational handling of Gaillardia cultivars. Additional self treatment with a body lotion containing extracts of Arnica worsened the skin lesions. Epicutaneous tests with different Gaillardia sesquiterpene lactones revealed spathulin to be the responsible sensitizer. Cross reactions were obtained with telekin, alantolactone, parthenolide, isoalantolactone and carabrone.
