摘要
目的:总结面部脂溢性皮炎和酒渣鼻的皮肤镜特征,并评估皮肤镜在二者鉴别诊断中的意义。方法:收集2014年1月—6月在该科就诊的17例面部脂溢性皮炎和19例酒渣鼻患者,行皮肤镜检查,评估皮肤镜下皮损背景、血管形态、血管分布、毛囊性异常等特征出现的频率,以及各特征对于诊断两种疾病的敏感度及特异度。结果:面部脂溢性皮炎常见的皮肤镜表现为红色或黄红色背景,灶性分布的非典型血管或线性分支状血管,毛囊周围淡黄红色油滴状晕,后者在之前的文献中尚无报道;酒渣鼻在皮肤镜下常表现为深红色背景,线性分支状血管弥漫性分布组成多角形血管网,部分患者可见毛囊性脓疱。结论:面部脂溢性皮炎和酒渣鼻具有不同的皮肤镜特征,皮肤镜在二者的诊断和鉴别诊断中具有良好的应用价值。
Objective： To describe the dermoscopic features of facial seborrheic dermatitis and rosacea, and evaluate its ap- plication in the diagnosis and differential diagnosis of the two diseases. Methods： Seventeen patients with facial seborrheic dermatitis and nineteen patients with rosacea were collected in our hospital from January to June in 2014. All the patients were given dermoscopic examination, in order to evaluate the frequency of the dermoscopic features （background of skin le- sions, vascular morphology, blood vessel distribution and hair follicle abnormalities）, and the sensitivity and specificity of these features for the diagnosis of the two diseases. Results： The characteristic dermoscopic changes of facial seborrheic der- matitis were red or red-yellowish in the background, with focal atypical vessels and linear arborizing vessels, perifollicular red halo. In contrast, rosacea was characterized by the dark red background and polygonal vessels. Conclusion： Facial seborrheic dermatitis and rosaeea show different dermoscopic patterns. Dermoscopy may be a valuable tool in the diagnosis and differen- tial diagnosis of facial seborrheic dermatitis and rosacea.
