Occupational allergic contact dermatitis caused by decorative plants.
12 cases of occupational allergic contact dermatitis caused by decorative plants were diagnosed in a 14-year period. The patients were middle-aged, and their average exposure time was 13 years. The plant families and plants causing occupational contact dermatitis were Compositae (5 patients; chrysanthemum, elecampane, gerbera, feverfew), Alstroemeriaceae (5 patients, Alstroemeria), Liliaceae (4 patients; tulip, hyacinth), Amaryllidaceae (2 patients; narcissus) and Caryophyllaceae (2 patients; carnation, cauzeflower). The known chemical allergens causing dermatitis were tuliposide-A and sesquiterpene lactones, such as alantolactones and parthenolide, in the Liliaceae and Compositae families. 7 of the 12 patients were able to continue their work; 5 were not because of severe relapses of skin symptoms. The plant allergen and extract series currently available are of great help in the diagnosis.
