Nail dermoscopy (onychoscopy) during physical examination assists in correct diagnosis. Often further magnifications are necessary for an effective differential diagnosis. With the addition of a red light to the dermoscope, important vascular features can be visualized.
To describe common features observed at onychoscopy with a new device that combines the regular white light with the red light illumination, demonstrating that it is useful for diagnosis of nail disorders.
We enrolled 33 consecutive patients referred to the Nail Diseases Dermatology Unit of the University of Modena and Reggio Emilia and to the Outpatient Consultation for Nail Disease of the Dermatology Unit of the University of Bologna. Patients were assessed with a standard hand-held dermoscope and at the red light dermoscope. Dermoscopic images were collected.
The new prototype was used during daily clinical practice and allowed a more accurate visualization of some details that classic onychoscopy can miss. In particular, with the help of the red light it was possible to better visualize nail lesions that were characterized by some kind of colour change or vascular alterations.
The new device of red light for vascular pattern onychoscopy can be a new investigation method to observe nail alterations, especially due to vascular pattern, even with low magnification, without the necessity to use higher resolutions.
体检时的指甲皮肤镜（甲镜检查）有助于正确诊断。为了进行有效的鉴别诊断，通常需要进一步放大。在皮肤镜上增加红光后，可以观察到重要的血管特征。
描述一种新设备在甲镜检查中观察到的常见特征，该设备将常规白光与红光照明相结合，证明其对诊断指甲疾病有用。
我们招募了 33 名连续就诊于摩德纳和雷焦艾米利亚大学皮肤科指甲疾病门诊和博洛尼亚大学皮肤科指甲疾病门诊的患者。患者接受了标准手持皮肤镜和红光皮肤镜检查。收集了皮肤镜图像。
新型原型在日常临床实践中得到了应用，能够更准确地观察到经典甲镜检查可能遗漏的一些细节。特别是，借助红光，可以更好地观察到某些颜色变化或血管改变特征的指甲病变。
新的红光血管模式甲镜检查设备可以成为一种新的观察指甲变化的检查方法，特别是由于血管模式，即使在低放大倍率下，也无需使用更高的分辨率。
