Chemotherapy-induced alopecia (CIA) can seriously affect the quality of life of cancer patients. Trichoscopic patterns and confocal microscopy (RCM) features of CIA have been scarcely studied. This study aimed to investigate the dermoscopic and RCM features of CIA in 19 females and 5 males, with CIA due to current or recent chemotherapy.
Patients with CIA and current or recent (within 2 months) history of chemotherapy treatment were enrolled. After clinical examination, standard pictures were taken by digital camera (SLR Canon PowerShot G10) and trichoscopic images were captured by the Handyscope device (20x). Images of RCM were acquired by VivaScope 3000 with the VivaStack option. The trichoscopic and confocal images were acquired by three independent observers after central parting on three areas: vertex, middle, and frontal scalp.
A total of 24 patients were enrolled. CIA has features of anagen effluvium at trichoscopy but with low frequency of yellow dots and prominence of black dots. The simultaneous presence of pseudo-monilethrix and black dots at trichoscopy confirms the hypothesis that chemotherapy insults the hair follicle intermittently. At RCM, the presence of abnormal hair shaft morphology highlights that the insults affect hair shaft production.
These are the first data in this field, so further studies with a higher number of patients analyzed are needed to confirm these findings.
化疗所致脱发(CIA)会严重影响癌症患者的生活质量。CIA的毛发镜检查模式和共聚焦显微镜(RCM)特征鲜有研究。本研究旨在调查19名女性和5名男性CIA患者的皮肤镜和RCM特征,这些患者因正在进行或近期接受化疗而出现CIA。
纳入有CIA且有正在进行或近期(2个月内)化疗治疗史的患者。临床检查后,用数码相机(佳能PowerShot G10单反相机)拍摄标准照片,并用Handyscope设备(20倍)采集毛发镜图像。用配备VivaStack选项的VivaScope 3000获取RCM图像。由三名独立观察者在头顶、中部和额部头皮三个区域进行中央分缝后采集毛发镜和共聚焦图像。
共纳入24名患者。CIA在毛发镜检查时有生长期脱发的特征,但黄点出现频率低,黑点突出。毛发镜检查时假性念珠状发和黑点同时存在,证实了化疗间歇性损伤毛囊的假说。在RCM检查中,异常毛干形态的存在突出表明损伤影响毛干生成。
这是该领域的首批数据,因此需要进一步研究分析更多患者以证实这些发现。
