Polymorphous light eruption (PMLE) is a common acquired disease entity belonging to the idiopathic photodermatoses that is uncommonly considered in the Hispanic population. The pathogenesis of the disease and the mechanism of adaptation in skin (hardening phenomenon) have yet to be elucidated. PMLE is characterized by recurrent abnormal delayed reactions to sunlight ranging from pruritic erythematous papules, papulovesicles and plaques to erythema multiforme. It commonly occurs in the spring or early summer with a predilection for females. A Pubmed review of the literature shows no case reports or literature regarding PMLE in Hispanics. To the best of our knowledge, we report the first case of a 41-year-old Hispanic female diagnosed with PMLE. A high index of suspicion must remain in this group. Additional studies reviewing epidemiology in this group and detailing similar cases may be suggested.
多形性日光疹（PMLE）是一种常见的获得性疾病实体，属于特发性光皮肤病，在西班牙裔人群中较少被考虑。该疾病的发病机制以及皮肤适应机制（硬化现象）尚未阐明。PMLE的特征是对阳光反复出现异常延迟反应，从瘙痒性红斑丘疹、丘疹水疱和斑块到多形红斑。它通常发生在春季或初夏，女性更易患病。对文献的PubMed综述显示，没有关于西班牙裔人群中PMLE的病例报告或文献。据我们所知，我们报告了首例被诊断为PMLE的41岁西班牙裔女性病例。对此群体必须保持高度怀疑指数。可能建议开展更多研究，回顾该群体的流行病学情况并详细描述类似病例。
