Two elderly individuals suffering from acute recurrent dermatitis of light-exposed skin between spring and autumn were shown to be allergic to feverfew (Tanacetum parthenium) of the Compositae family. Patch tests revealed not only strong reactions to the plant and its constituent parthenolide but also a number of cross-reactions to related species. The source of this contact allergy was dried airborne plant particles that attached themselves to the skin during long periods outdoors. Differentiation between patterns of airborne contact dermatitis and persistent light reaction is possible by several distinct observations, i.e., in patients with airborne contact dermatitis: a) Patch tests with Compositae plant extracts and constituents will be positive. b) There will be no skin lesions in winter. c) Skin regions that are usually not impaired during light exposure will also be involved: the upper eyelids, the retroauricular region, the shady area beneath the chin.
两名老年患者在春秋季节患有急性复发性日光暴露皮肤性皮炎，结果显示他们对菊科植物小白菊（Tanacetum parthenium）过敏。斑贴试验不仅显示对该植物及其成分小白菊内酯有强烈反应，还显示对相关物种有一些交叉反应。这种接触性过敏的来源是干燥的空气传播植物颗粒，它们在长时间户外活动时附着在皮肤上。通过一些不同的观察结果可以区分空气传播性接触性皮炎和持续性光反应的模式，即对于空气传播性接触性皮炎患者：a）用菊科植物提取物和成分进行斑贴试验将呈阳性。b）冬季不会出现皮肤病变。c）通常在日光暴露时不受损的皮肤区域也会受累：上眼睑、耳后区域、下巴下方的阴凉区域。
