Diagnosis of pityriasis lichenoides et varioliformis acuta (PLEVA) is based on the characteristic pattern of lesions in different stages of development, ranging from erythematous maculopapules to papules with a crusted and/or necrotic centre. However, it may raise the differential diagnosis with other entities. It is therefore not uncommon to have to perform skin biopsies to reach a diagnosis, including in infants. In this study, we report the cases of three patients with PLEVA, highlighting the correlations between the clinical, dermoscopic and histological features. Observation of the dermatoscopic findings described, such as punctate or glomerular vessels and erythematous globules surrounding a homogeneous orange or crusty central area, may allow for a rapid diagnosis, avoiding the need for invasive techniques.
急性痒疹性苔藓样糠疹（PLEVA）的诊断基于不同发展阶段皮损的特征性模式，从红斑性斑丘疹到有结痂和/或坏死中心的丘疹。然而，它可能会引起与其他实体的鉴别诊断。因此，为了做出诊断，包括对婴儿进行皮肤活检并不罕见。在这项研究中，我们报告了三例 PLEVA 患者的病例，强调了临床、皮肤镜和组织学特征之间的相关性。观察到描述的皮肤镜检查结果，如点状或肾小球血管和围绕均匀橙色或结痂中央区域的红斑性小球，可能有助于快速诊断，避免使用侵入性技术。
