Contact eczema is one of the most frequent dermatological affections, regardless of age and sex. In typical cases, the diagnosis is usually easy, but it may be less so where there are atypical factors, in particular locations and with complications or unusual etiological data. In fact, the first condition in making a diagnosis is to suspect that there is the possibility of contact allergy. As an example, it should be remembered that allergy to benzalkonium can be diagnosed after a mean time of 87 months of evolution. The present availability of standardised allergens for testing for contact allergens has greatly changed the diagnostic possibilities. The allergens that are most often the cause in the genital region are perfumes, chlorhexidine, hexamidine, benzylalkonium chloride and latex. Only recognition of the allergen and its removal are used and sufficient to obtain recovery.
接触性湿疹是最常见的皮肤病之一，不分年龄和性别。在典型病例中，诊断通常很容易，但在存在非典型因素、特定部位、伴有并发症或病因数据不寻常的情况下，诊断可能会比较困难。事实上，做出诊断的首要条件是怀疑存在接触性过敏的可能性。例如，应记住，对苯扎氯铵的过敏在平均87个月的病程后才能被诊断出来。目前可用于检测接触性过敏原的标准化过敏原极大地改变了诊断的可能性。在生殖器区域最常见的过敏原是香料、氯己定、己脒定、苯扎氯铵和乳胶。仅识别过敏原并将其去除就足以实现康复。
