Temporary henna tattoos have become increasingly popular, particularly among children and teenagers. The word "henna" is of Persian origin, and it is prepared from the plant belonging to the family . Concerning allergic reactions, natural henna paste is rarely responsible for contact dermatitis, which is more frequent if paraphenylenediamine (PPD) is added to the paste. The authors present a case of female child with erythematous exanthems that appeared after the application of black henna tattoo. A diagnosis of contact dermatitis to black henna tattoo was hypothesised. Epicutaneous tests were performed at the Immunoalergology Department of the Coimbra University Hospital using standard European battery and natural henna paste. The tests revealed positive reaction to PPD.
临时纹身在儿童和青少年中越来越受欢迎。“henna”这个词来源于波斯语，是从指甲花属植物中提取的。关于过敏反应，天然指甲花膏很少引起接触性皮炎，如果在膏体中加入对苯二胺（PPD）则更常见。作者报告了一例女性儿童在应用黑色指甲花纹身后面部出现红斑性皮疹的病例。假设为黑色指甲花纹身引起的接触性皮炎。在科英布拉大学医院的免疫过敏科进行了斑贴试验，使用了标准的欧洲试剂盒和天然指甲花膏。试验显示对 PPD 呈阳性反应。
