Abstrakt: Introduction: 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.
Methods: 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.
Results: 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.
Conclusion: These are the first data in this field, so further studies with a higher number of patients analyzed are needed to confirm these findings.
Competing Interests: The authors have no conflicts of interest to declare.
