Abstract
While allergic contact dermatitis from Compositae, mostly caused by sesquiterpenelactones, is relatively common, immediate-type hypersensitivity is reported less frequently. A 42-year old female florist is reported who first developed contact urticaria to pollen of dandelion. Later, whealing occured also on non-exposed skin sites and delayed-type allergic bronchial asthma developed after exposure to a variety of compositae pollen, such as chrysanthemum, golden rod, marguerite. The diagnosis was confirmed by positive skin prick tests with native material and extracts, by the detection of specific IgE-antibodies and positive bronchial provocation tests with three selected species. The patient had to stop working, because sufficient avoidance of airborne exposure to pollens of these very popular decorative plant was not considered practical.
