Polymorphous light eruption is the most common photodermatosis, with a prevalence of as high as 10-20% in Western Europe and in the USA. It starts during the second and third decades of life. Although not life-threatening it can severely impair the quality of life, in particular during leisure activities and in outdoors workers. Polymorphous light eruption belongs to the group of so-called idiopathic photodermatoses. This term denotes dermatoses that occur in otherwise healthy individuals from exposure to sunlight or artificial light without the intervention of an exogenous photosensitizing agent. These diseases have two factors in common: they are precipitated by ultraviolet or visible radiation; and their exact pathomechanism remains obscure but is presumably immunologic in nature.
多形性日光疹是最常见的光皮肤病，在西欧和美国的患病率高达10%至20%。它始于人生的第二个和第三个十年。虽然不危及生命，但它会严重损害生活质量，尤其是在休闲活动期间以及户外工作者中。多形性日光疹属于所谓的特发性光皮肤病组。该术语指的是在没有外源性光敏剂干预的情况下，因暴露于阳光或人造光而在其他方面健康的个体中发生的皮肤病。这些疾病有两个共同因素：它们由紫外线或可见光辐射诱发；其确切的发病机制仍然不明，但推测本质上是免疫性的。
