带状疱疹样扁平苔藓是皮肤扁平苔藓的一种变体,可能在带状疱疹治愈的部位发展,也可能自发进化,以前没有带状疱疹或水痘-带状疱疹病毒感染史。扁平苔藓是一种免疫介导的疾病,影响皮肤和粘膜。尽管如此,其确切病因尚不清楚。病变由多边形组成,瘙痒,平顶丘疹,可能合并形成斑块。这是一例39岁的女性,其躯干右侧有三个月的瘙痒性皮肤病变史。在皮肤病学检查中,有很大的,离散,带状,色素沉着过度,躯干和腹部右侧的Blaschko线条后出现丘疹。从病变处进行的活检的组织学检查显示,锯齿网脊,带状炎症浸润,确认诊断为扁平苔藓,并接受局部类固醇治疗。根据调查结果,一个刨床,遵循Blaschko线分布而不是皮球分布的瘙痒性皮疹应引起对带状疱疹样扁平苔藓的怀疑。
Zosteriform lichen planus is a variant of cutaneous lichen planus that may develop at the site of healed herpes zoster or may evolve spontaneously with no previous history of herpes zoster or varicella-zoster virus infection. Lichen planus is an immune-mediated disorder that affects the skin and mucous membrane. Nonetheless, its exact etiology remains unclear. The lesion consists of polygonal, pruritic, flat-topped papules that may coalesce to form a plaque. This is a
case of a 39-year-old female presenting with a three-month history of pruritic skin lesion over the right side of her trunk. On dermatological examination, there were large, discrete, band-like, hyperpigmented, papular patches following Blaschko\'s lines on the right side of the trunk and abdomen. The histological examination of a biopsy taken from the lesion showed hypergranulosis, sawtooth rete ridges, band-like inflammatory infiltrate, confirming the diagnosis of lichen planus and was treated with topical steroids. Based on the findings, a planer, pruritic skin rash that follows Blaschko\'s lines distribution rather than dermatomal distribution should raise the suspicion of zosteriform lichen planus.
