Vitiligo affects approximately 1% of the general population without racial, sexual, or regional differences. However, studies of segmental vitiligo have been few and the number of patients limited.
The aim of this study was to analyze the clinical features of patients with segmental vitiligo.
We evaluated sex, age at onset, age at initial visit, character of the initial lesion, status of progression, precipitating factors, involved sites, dermatomal distribution, family history, Koebner phenomenon, presence of poliosis, dominant hand, and associated diseases.
Segmental vitiligo had an early onset, rapid progression, no specific precipitating factors, and linear spreading in the affected dermatomal area. The most commonly involved dermatome was the trigeminal. Only a few patients had an associated autoimmune disease.
The clinical features of segmental vitiligo differ from those of nonsegmental vitiligo; pathogenesis may also differ.
白癜风影响约1%的普通人群，无种族、性别或地区差异。然而，节段型白癜风的研究较少，患者数量有限。
本研究旨在分析节段型白癜风患者的临床特征。
我们评估了性别、发病年龄、初诊年龄、初始皮损特征、进展情况、诱发因素、受累部位、皮节分布、家族史、同形反应、白发情况、优势手及相关疾病。
节段型白癜风起病早、进展快、无特定诱发因素，在受累皮节区域呈线性扩展。最常受累的皮节是三叉神经。仅有少数患者伴有自身免疫性疾病。
节段型白癜风的临床特征与非节段型白癜风不同；发病机制可能也不同。
