Pityriasis lichenoides et varioliformis acuta (PLEVA) is a rare cutaneous eruption of erythematous macules and papules distributed over the flexural surfaces and the trunk. Histopathologic analysis is useful in diagnosis, and dermoscopic findings have been described in several small case series. We present a case of a mid-20s female who was diagnosed with PLEVA based on clinical and histopathological findings, and we also demonstrate a unique dermoscopic finding. Additionally, we review the current literature detailing dermoscopy findings with associated histopathology in PLEVA and pityriasis lichenoides chronica (PLC).
急性痘疮样苔藓样糠疹（PLEVA）是一种罕见的皮肤疹，表现为分布于屈侧皮肤表面和躯干的红斑性斑疹和丘疹。组织病理学分析对诊断有帮助，并且在几个小病例系列中已经描述了皮肤镜检查结果。我们报告一例25岁左右的女性病例，该病例根据临床和组织病理学检查结果被诊断为PLEVA，并且我们还展示了一种独特的皮肤镜检查结果。此外，我们回顾了当前详细阐述PLEVA和慢性苔藓样糠疹（PLC）的皮肤镜检查结果及其相关组织病理学的文献。
