BACKGROUND
Solar urticaria manifests itself immediately after solar or artificial light exposure and disappears a little later. Histopathologic findings of solar urticaria are essentially identical to those of classic urticaria.
CASE REPORT
We report a 41-year-old man who developed urticarial lesions some hours after sunlight exposure, which resolved after approximately 1 week. Histologic examination of the lesions evidenced a leukocytoclastic vasculitis.
CONCLUSION
In a literature review we found one case of solar urticaria with histologic aspects of leukocytoclastic vasculitis.
背景
日光性荨麻疹在暴露于日光或人造光后立即出现，随后不久消失。日光性荨麻疹的组织病理学表现与经典荨麻疹基本相同。
病例报告
我们报告一名41岁男性，其在日光照射数小时后出现荨麻疹皮损，约1周后消退。皮损的组织学检查显示为白细胞破碎性血管炎。
结论
在文献综述中，我们发现1例具有白细胞破碎性血管炎组织学表现的日光性荨麻疹病例。
