Abstract

Objective To evaluate the role of dermoscopy in the confirmation of vitiligo diagnosis and evaluate its role in disease prognosis and its clinical stability. Background Vitiligo is an acquired disorder characterized by circumscribed depigmented macules and patches with or without leukotrichia. Dermoscopy by magnifying the clinical image many folds allows the appreciation of subtle features invisible to the naked eye. Dermoscopy has been reported to be beneficial in certain circumstances in vitiligo, including diagnosis of early vitiligo, assessment of the stage of the disease, assessment of treatment response by detecting clinically in apparent leukotrichia, especially in the segmental variant, and differentiation of guttate vitiligo from idiopathic guttate hypomelanosis. Patients and methods The study was conducted in Dermatology Outpatient Clinic of Menoufia University Hospital on 30 clinically diagnosed patients with vitiligo, including clinically stable and unstable vitiligo cases. The patients were subjected to full history taking with special consideration to family history of vitiligo disease, general, dermatological, and dermoscopic examinations using Derma lite 4 device. Results There is a statistically significant relation between clinical stability and absent pigment network, perifollicular depigmentation, and presence of marginal hyperpigmentation. Conclusion Dermoscopy can be used to monitor the disease activity and can be regarded as a reliable noninvasive simple tool to evaluate clinical stability of vitiligo.
