摘　　要：目的初步探究毛母细胞瘤皮肤镜结构特征,为临床诊断毛母细胞瘤提供思路。方法收集2018年11月至2021年7月在武汉市第一医院就诊的5例经组织病理确诊的毛母细胞瘤患者皮肤镜数据资料,分析其镜下结构特征。结果根据肉眼观察有无色素,将毛母细胞瘤分为色素型(3例)和无色素型(2例)两类。在3例色素型毛母细胞瘤中,皮肤镜下可见蓝灰色卵圆形巢(3例)、分支状血管(2例)、蓝灰色小球(2例)、亮白色无结构区(2例)、同心性结构(1例)、溃疡(1例),均无黄白色均质结构。2例无色素型毛母细胞瘤中,皮肤镜下可见分支状血管2例、黄白色均质结构2例、亮白色无结构区2例,蓝灰色小球1例,均未见溃疡及蓝灰色卵圆形巢。结论色素型与无色素型毛母细胞瘤具有不同的皮肤镜特征,皮肤镜可以为毛母细胞瘤提供初步的诊断线索。Objective To preliminarily investigate dermoscopic characteristics of trichoblastoma,and to provide ideas for clinical diagnosis of trichoblastoma.Methods Clinical data were collected from 5 patients with trichoblastoma who underwent both dermoscopic and histopathological examinations in Wuhan No.1 Hospital from November 2018 to July 2021,and dermoscopic features were analyzed retrospectively.Results According to the presence or absence of pigments,trichoblastoma was divided into 2 subtypes:pigmented trichoblastoma(3 cases)and non-pigmented trichoblastoma(2 cases).Dermoscopic examination of the 3 cases of pigmented trichoblastoma showed blue-gray ovoid nests(3 cases),arborizing vessels(2 cases),blue-gray globules(2 cases),bright white structureless areas(2 cases),concentric structures(1 case)and ulcers(1 case);no yellow-whitish homogenous structure was found.As for non-pigmented trichoblastoma,dermoscopic features included arborizing vessels(2 cases),yellow-whitish homogenous structures(2 cases),bright white structureless areas(2 cases)and blue-gray globules(1 case);no ulcers or blue-gray ovoid nests were observed in either case.Conclusion Dermoscopic patterns differ between pigmented and non-pigmented trichoblastoma,so dermoscopy can provide preliminary diagnostic clues for trichoblastoma.
