Lichen striatus is a rare dermatological condition seen in children. The exact etiology of this self-limiting eruption is unknown. A combination of genetic predisposition with an infectious trigger is the most accepted hypothesis for the etiology. Treatment is typically not necessary, as the disease is self-limiting. Treatment options with topical low to mid-potency corticosteroids may be used for symptomatic treatment of pruritus, however, it does not alter the course of the disease or post-inflammatory dyspigmentation. Successful treatment of skin lesions with calcineurin inhibitors is reported in isolated studies. The rapidly growing lesion of lichen striatus can cause considerable parental anxiety. Familiarity with this condition for primary care pediatricians is necessary to make the correct diagnosis and to alleviate parental anxiety. Here, we present a case of lichen striatus albus, a variant of lichen striatus, in a five-year-old girl presenting as a skin rash.
线状苔藓是一种在儿童中罕见的皮肤病。这种自限性皮疹的确切病因尚不清楚。遗传易感性与感染诱因相结合是目前最被认可的病因假说。由于该病具有自限性，通常无需治疗。外用低至中效糖皮质激素可用于瘙痒症状的治疗，然而，这并不会改变疾病进程或炎症后色素沉着。个别研究报道了使用钙调神经磷酸酶抑制剂成功治疗皮肤病变的案例。线状苔藓迅速发展的皮损会引起家长相当大的焦虑。基层儿科医生熟悉这种疾病对于做出正确诊断和缓解家长焦虑很有必要。在此，我们报告一例五岁女童出现皮疹，诊断为线状苔藓的白色变种——白线状苔藓。
