Dermoscopy is a diagnostic tool that has been introduced into small animal dermatology for the evaluation of hair and the skin surface. To the best of the authors' knowledge, the use of this technique on horses and the dermoscopic appearance of equine hair and skin have yet to be reported.
HYPOTHESIS/OBJECTIVES: To assess the feasibility of dermoscopy, and to describe hair and skin surface features of healthy warmblood horses.
Thirty four client-owned, healthy adult horses.
Six body regions (head, neck, dorsal thorax, ventral thorax, croup and mane) were examined with a smartphone-attached, hand-held polarized light dermoscope at 20-fold magnification. Smartphone-collected images were evaluated to determine the overall hair density, large and thin primary hair densities and diameters, and skin surface characteristics. Software was used to measure large and thin primary hair shaft thickness. Comparisons between body regions, breeds and sexes were made.
Dermoscopic examination of the equine skin surface was feasible and easy to perform. At 20-fold magnification thick, straight hair shafts emerging from single follicular openings were observed. In between these, thinner straight hair shafts were present in all evaluated regions. Hair shafts of the head and the mane were significantly thicker but less dense compared to other regions. Skin pigmentation and variable perifollicular discolouration were present.
Dermoscopy may represent a valuable technique for the dermatological examination of the equine patient.
皮肤镜是一种已被引入小动物皮肤病学用于评估毛发和皮肤表面的诊断工具。据作者所知，该技术在马匹上的应用以及马的毛发和皮肤的皮肤镜表现尚未见报道。
假设/目的：评估皮肤镜检查的可行性，并描述健康温血马的毛发和皮肤表面特征。
34匹客户拥有的健康成年马。
使用连接智能手机的手持式偏振光皮肤镜，以20倍放大倍数检查六个身体部位（头部、颈部、胸背部、胸前部、臀部和鬃毛）。对智能手机采集的图像进行评估，以确定整体毛发密度、粗毛和细毛的密度及直径，以及皮肤表面特征。使用软件测量粗毛和细毛的毛干厚度。对身体部位、品种和性别进行比较。
对马皮肤表面进行皮肤镜检查是可行且易于操作的。在20倍放大倍数下，观察到从单个毛囊开口处长出的粗直毛干。在这些毛干之间，所有评估区域都存在较细的直毛干。与其他区域相比，头部和鬃毛的毛干明显更粗但密度更低。存在皮肤色素沉着和毛囊周围不同程度的变色。
皮肤镜检查可能是对马进行皮肤病学检查的一项有价值的技术。
