儿童面部获得性色素沉着斑7例

Acquired facial hyperpigmented macules in children:seven case reports

报道7例以额部色素沉着为特征的患儿。7例患儿中,男2例,女5例,发病年龄9~24(12.43±5.32)个月,病程1~4(2.57±1.27)个月。皮肤科检查:患儿额题部散在分布数量不等的咖啡色斑点、斑片,形状不规则,表面未见明显鳞屑。皮肤镜检查:可见多发的假网状黄褐色色素斑片,边界不规则,部分皮损可见线状血管。诊断:儿童面部获得性色素沉着斑。均未予特殊处理,随访2年,2例色素沉着斑完全消退,4例不同程度减轻,1例无变化。结合文献及本文病例推测儿童面部获得性色素沉着斑是一种独立的疾病。

To report 7 Chinese children with characteristic hyperpigmented macules on the forehead and temples.Among the 7 cases,there were 2 males and 5 females,with the age at onset ranging from 9 to 24 months(12.43±5.32 months),and the disease duration being 1-4 months(2.57±1.27 months).Skin examination revealed that the children presented with varying numbers of irregular brown macules and patches scattered on their foreheads and temples,without obvious desquamation.Dermoscopic examination revealed multiple yellowish-brown patches with irregular borders,and linear vessels were observable in some skin lesions.A diagnosis of acquired facial hyperpigmented macules was made in these children.The children received no treatment.After 2 years of follow-up,hyperpigmented macules completely subsided in 2 cases and regressed to varying degrees in 4 cases,while 1 case exhibited no changes in the skin lesions.Considering the literature and the cases discussed in this article,it is hypothesized that acquired facial hyperpigmented macules in young children may represent an independent condition.
