Polymorphous light eruption is an acquired photodermatosis, whose causal factors have not yet been identified. The diagnosis is based on the clinical picture and on histology. During the symptomless periods, photo-testing is the most important technique to confirm the diagnosis, since there are no specific laboratory parameters. Regarding our own patients, typical lesions could be provoked by UVA in 50%, by UVB in 20% and by both in 30%. The majority of the patients can be protected during the summer season by intermittent preventive photo(chemo)therapy.
多形性日光疹是一种后天性光皮肤病，其病因尚未明确。诊断基于临床表现和组织学检查。在无症状期，由于没有特定的实验室指标，光试验是确诊的最重要技术。就我们自己的患者而言，50%的患者典型皮损可由UVA诱发，20%由UVB诱发，30%由两者共同诱发。大多数患者在夏季可通过间歇性预防性光（化学）疗法得到保护。
