A 35-year-old woman would develop urticarial lesions over one to four hours after irradiation with sunlight or artificial ultraviolet radiation. Lesions could persist for days before resolving. Although lesions were morphologically typical of solar urticaria, their evolution and resolution were both much slower than expected. Histologically, the lesions showed leukocytoclastic vasculitis. This unexpected finding suggests the possibility that there may be novel mechanisms involved in the pathogenesis of some cases of solar urticaria.
一名35岁女性在接受阳光或人工紫外线照射后1至4小时会出现荨麻疹皮损。皮损可持续数天才能消退。尽管皮损在形态上是日光性荨麻疹的典型表现，但其演变和消退速度均比预期慢得多。组织学上，皮损表现为白细胞破碎性血管炎。这一意外发现提示，某些日光性荨麻疹病例的发病机制可能涉及新的机制。
