背景:纹状体苔藓是一种良性皮肤病,主要影响儿童。这种情况模仿许多其他皮肤病。
目的:本文的目的是使儿科医生熟悉扁平苔藓的临床表现,以避免误诊,不必要的调查,不必要的转介,以及纹状体地衣管理不善.
方法:于2023年6月在PubMed临床查询中使用关键术语“纹状体苔藓”进行了搜索。搜索策略包括所有观察性研究,临床试验,以及在过去十年内发表的评论。本评论仅包括在英语文献中发表的论文。从上述搜索中检索到的信息用于本文的汇编。
结果:扁平苔藓是一种良性的自限性T细胞介导的皮肤病,其特征是主要见于儿童的线性炎性丘疹。发病通常是突然的,症状很少或没有。典型的扁平苔藓纹状体的喷发由离散的,肤色,粉色,红斑,或者暴力,平顶,稍微升高,融合形成暗红色的光滑或有鳞丘疹,可能有鳞状,在几天到几周内中断或连续的带。尽管身体的任何部分都可能参与其中,四肢是好的部位。通常,皮疹是孤独的,单边,并遵循Blaschko的路线。在深色皮肤的个体中,皮肤病变可能在发病时色素减退。指甲可能会单独受到影响,或者,更常见的是,伴随着纹状体苔藓的皮肤病变。扁平苔藓纹状体的鉴别诊断很多,其他疾病的显着特征在本文中得到了强调。
结论:纹状体苔藓是一种自限性疾病,通常在一年内消退,没有残留的疤痕,但可能有短暂的炎症后色素沉着减退或色素沉着过度。因此,治疗可能是不必要的。对于希望接受美容治疗或瘙痒对症治疗的患者,可以使用低至中效价的局部皮质类固醇或局部免疫调节剂。褪色乳膏可用于炎症后色素沉着过度。
BACKGROUND: Lichen striatus is a benign dermatosis that affects mainly children. This condition mimics many other dermatoses.
OBJECTIVE: The purpose of this article is to familiarize pediatricians with the clinical manifestations of lichen striatus to avoid misdiagnosis, unnecessary investigations, unnecessary referrals, and mismanagement of lichen striatus.
METHODS: A search was conducted in June 2023 in PubMed Clinical Queries using the key term \"Lichen striatus\". The search strategy included all observational studies, clinical trials, and reviews published within the past ten years. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of this article.
RESULTS: Lichen striatus is a benign self-limited T-cell mediated dermatosis characterized by a linear inflammatory papular eruption seen primarily in children. The onset is usually sudden with minimal or absent symptomatology. The eruption in typical lichen striatus consists of discrete, skin- colored, pink, erythematous, or violaceous, flat-topped, slightly elevated, smooth or scaly papules that coalesce to form a dull red, potentially scaly, interrupted or continuous band over days to weeks. Although any part of the body may be involved, the extremities are the sites of predilection. Typically, the rash is solitary, unilateral, and follows Blaschko lines. In dark-skinned individuals, the skin lesions may be hypopigmented at onset. Nails may be affected alone or, more commonly, along with the skin lesions of lichen striatus. The differential diagnoses of lichen striatus are many and the salient features of other conditions are highlighted in the text.
CONCLUSIONS: Lichen striatus is a self-limited condition that often resolves within one year without residual scarring but may have transient post-inflammatory hypopigmentation or hyperpigmentation. As such, treatment may not be necessary. For patients who desire treatment for cosmesis or for the symptomatic treatment of pruritus, a low- to mid-potency topical corticosteroid or a topical immunomodulator can be used. A fading cream can be used for post-inflammatory hyperpigmentation.
