Abstract

Pigmented purpuric eruptions comprise a group of benign dermatoses that are characterized clinically by pinpoint petechiae and purpura on a hyperpigmented base and histologically by capillaritis. The etiology of this group of disorders is unknown, although aberrant cell-mediated immunity has been proposed. Pigmented purpuric eruptions are well characterized in the pediatric population. In this case series we present three children with these disorders and review the clinical subtypes of pigmented purpuric eruptions that have been described in the literature.

摘要

色素性紫癜性皮疹是一组良性皮肤病，临床特征为在色素沉着的基础上出现针尖大小的瘀点和紫癜，组织学特征为毛细血管炎。尽管有人提出这组疾病的病因是异常的细胞介导免疫，但其病因尚不清楚。色素性紫癜性皮疹在儿科人群中有明确的特征。在这个病例系列中，我们展示了三名患有这些疾病的儿童，并回顾了文献中描述的色素性紫癜性皮疹的临床亚型。
