A young girl presented with a hypopigmentation in the shape of the sun. During a holiday in Egypt 3 months before a non-permanent henna tattoo had been applied on her right upper arm. Three to 4 days later there was a severe cutaneous reaction followed by massive swelling of the arm. The lesion took 6 weeks to subside. Patch testing revealed positive reactions to para-phenylenediamine (PPD) but not to henna or any other standard allergen. Especially in Arabic countries PPD is a common additive in natural henna preparations to enhance the weak colouring properties of the natural henna dye. We conclude that henna preparations may contain 'hidden' allergens, such as PPD, which can provoke severe cutaneous reaction without any cosensitization to the henna dye itself.
一名年轻女孩出现了太阳形状的色素减退。在3个月前于埃及度假期间，她右上臂涂抹了非永久性的指甲花染料纹身。3至4天后，出现了严重的皮肤反应，随后手臂出现大量肿胀。病变花了6周才消退。斑贴试验显示对对苯二胺（PPD）呈阳性反应，但对指甲花染料或任何其他标准变应原呈阴性反应。特别是在阿拉伯国家，PPD是天然指甲花制剂中常见的添加剂，以增强天然指甲花染料较弱的染色性能。我们得出结论，指甲花制剂可能含有“隐藏”的变应原，如PPD，它可引发严重的皮肤反应，而无需对指甲花染料本身产生任何共致敏作用。
