Abstract

Background: Idiopathic guttate hypomelanosis (IGH) is a common pigmentary disorder encountered in older age group, causing cosmetic disfigurement with considerable psychological impact. Diagnosis is generally based on history and clinical features. In the situation of diagnostic dilemma, dermoscopic examination is the quick and easiest method to solve the clinical uncertainty and thereby avoid unnecessary biopsies. Objectives: The aims of the study were to describe the varied clinical presentations and to enumerate the dermoscopic features of IGH. Methods: Study was conducted after obtaining approval from Institutional Ethics Committee. All the patients presenting with IGH attending the Department of Dermatology were examined and enrolled for the study after taking written informed consent. Each subject was evaluated by detailed personal history, clinical examination and dermoscopic examination. Results: A total of 100 patients of IGH were included in the study. The most affected age group was 46–65 years (52%). Females were most commonly affected with M: F ratio 1:1.17. Different dermoscopic patterns of IGH documented were amoeboid (58.2%), feathery (19.1%), petaloid (14.5%) and nebuloid (8.2%). Ten percent of the patients showed more than one patterns. Conclusion: Dermoscope aids in evaluation of different patterns of IGH lesions, which helps to differentiate it from other hypopigmented conditions with considerable overlap in the site, morphology and clinical features. Dermoscopic analysis makes it easier to diagnose the disorder and subsequently plan for the appropriate treatment.
特发性点滴型低黑素症的皮肤镜分析:一项横断面研究
背景:特发性点滴型低黑素症(Idiopathic guttate hypelanosis, IGH)是一种常见于老年人群的色素疾病,其造成的美容毁容具有相当大的心理影响。诊断通常基于病史和临床特征。在诊断困难的情况下,皮肤镜检查是解决临床不确定性的最快速、最简单的方法,从而避免不必要的活检。目的:本研究的目的是描述不同的临床表现和列举皮肤镜特征的IGH。方法:研究在获得机构伦理委员会批准后进行。所有在皮肤科就诊的IGH患者在接受书面知情同意书后接受检查并入组研究。每位受试者通过详细的个人病史、临床检查和皮肤镜检查进行评估。结果:共纳入100例IGH患者。受影响最大的年龄组为46-65岁(52%)。女性最常见于M: F比1:1.17。不同皮肤镜下记录的IGH类型为变形虫(58.2%)、羽毛状(19.1%)、花瓣状(14.5%)和星云状(8.2%)。10%的患者表现出一种以上的模式。结论:皮肤镜有助于评估不同类型的IGH病变,有助于将其与其他在部位、形态和临床特征上有较大重叠的低色素状况区分。皮肤镜分析可以更容易地诊断这种疾病,并随后制定适当的治疗计划。
