Since the first description of adult blaschkitis (AB), the existence of this entity has been a matter of great debate.
To compare clinicopathological features of lichen striatus (LS) and AB cases.
We retrospectively reviewed the clinicopathological features of patients who clinically showed linear inflammatory dermatosis along Blaschko's lines based on a skin biopsy registry.
Through a process of clinicopathological differential diagnosis, 27 cases of LS, three of AB, eight of linear lichen planus, and two of linear psoriasis were identified. Clinicopathological differences between LS and AB were mostly insignificant except for age at onset and multiple site involvement. In these cases, females were affected more frequently than males. The mean age at onset was 31.6 years, and the most common involved site was the leg. The lesions lasted approximately 8.3 months with few relapses. The most common histopathological finding was perivascular infiltration followed by peri-appendageal infiltration.
Distinction between LS and AB appears to be unnecessary given their overlapping features.
自成人 Blaschkitis（AB）的首次描述以来，该实体的存在一直存在很大争议。
比较线状苔藓（LS）和 AB 病例的临床病理特征。
我们回顾性地审查了基于皮肤活检登记处的临床线性炎症性皮肤病患者的临床病理特征。
通过临床病理鉴别诊断过程，确定了 27 例 LS、3 例 AB、8 例线性扁平苔藓和 2 例线性银屑病。LS 和 AB 之间的临床病理差异大多不显著，除了发病年龄和多部位受累。在这些病例中，女性比男性更容易受到影响。发病平均年龄为 31.6 岁，最常见的受累部位是腿部。病变持续约 8.3 个月，很少复发。最常见的组织病理学发现是血管周围浸润，其次是附属器周围浸润。
鉴于其重叠特征，LS 和 AB 之间的区别似乎没有必要。
