Appearance of purpura acutely after sun exposure is rare. We report a 51-year-old woman who repeatedly developed an asymptomatic petechial eruption on her legs after strong sun exposure. Investigation found an action spectrum within the ultraviolet A waveband, and histological examination of an evoked lesion found features of capillaritis. We briefly review the literature on solar purpura, and suggest that it is a feature of several distinct conditions, rather than a single condition.
急性日晒后出现紫癜较为罕见。我们报告了 1 例 51 岁女性，在强烈日晒后，其腿部反复出现无症状性瘀点性皮疹。研究发现其在长波紫外线波段存在一个作用光谱，对诱发皮损的组织学检查发现毛细血管炎的特征。我们简要回顾了关于日晒性紫癜的文献，并提出其是几种不同疾病的特征，而非单一疾病。
