Lichen striatus (LS) is a well-known acquired linear inflammatory dermatosis. In 1990, Grosshans and Marot introduced the term 'adult blaschkitis' (AB), describing an eruption similar to LS occurring in an adult (adult LS). Does there really exist a new entity or a need for a new naming?
Two new cases of adult LS are described and the data from 16 earlier cases (12 AB and 4 adult LS) are reviewed.
The analysis of 18 adult patients with an acquired inflammatory blaschkolinear eruption reveals that females are affected two times as frequently as males. The mean age at onset is 44 years, the mean duration until spontaneous cure 8.7 months. Relapses occur in 27.7%. In 78%, the eruption is localized on the trunk, in 55% on the arms and in 50% on the legs. Multilinearity is found in 100% if the eruption is on the trunk, and 61.5% if it is on the limbs. Neither clinical nor morphological differences exist between AB and adult LS.
There are no convincing characteristics which justify creating a new name or even a new entity. AB may be the same as LS, a well-known acquired linear inflammatory dermatosis, which--as has been shown now--does not occur so rarely in adults. However, the etiology of this entity remains obscure.
线状苔藓（LS）是一种广为人知的后天性线状炎症性皮肤病。1990年，格罗斯汉斯和马罗引入了“成人线状苔藓样疹”（AB）这一术语，用于描述在成人中出现的类似于线状苔藓的皮疹（成人线状苔藓）。真的存在一种新的疾病实体或需要一个新的命名吗？
描述了2例成人线状苔藓的新病例，并回顾了16例早期病例（12例成人线状苔藓样疹和4例成人线状苔藓）的数据。
对18例患有后天性炎症性线状苔藓样疹的成年患者的分析显示，女性受影响的频率是男性的两倍。平均发病年龄为44岁，自发痊愈的平均病程为8.7个月。复发率为27.7%。78%的皮疹局限于躯干，55%在手臂，50%在腿部。如果皮疹在躯干，100%表现为多线性；如果在四肢，则为61.5%。成人线状苔藓样疹和成人线状苔藓在临床和形态学上均无差异。
没有令人信服的特征能证明需要创造一个新的名称甚至一个新的疾病实体。成人线状苔藓样疹可能与线状苔藓相同，线状苔藓是一种广为人知的后天性线状炎症性皮肤病，正如现在所显示的，在成人中并不罕见。然而，该疾病实体的病因仍不清楚。
