Abstract
Dermoscopy is a noninvasive, efficient and inexpensive tool used to aid diagnosis of skin conditions such as vitiligo. Furthermore, it aids in tracking patient progress, treatment response and disease activity. Vitiligo can be diagnosed on dermoscopy by the presence of white structureless areas signifying hypopigmentation with a typical glowing appearance. Other typical features are perilesional and perifollicular hyperpigmentation, pigmentation networks and leucotrichia. In total, 15 studies were reviewed to determine the dermoscopic signs of the three main stages of disease activity: active, stable and repigmenting vitiligo. Features that differentiate active, stable and repigmenting vitiligo are reviewed and discussed in this article. Notably, there is a conflict in the literature between various dermoscopic features and which type of vitiligo they are truly indicative of. However, dermoscopy can be coupled with other clinical, biological and physiological markers to strengthen diagnostic accuracy.
