Fluorescence-advanced videodermatoscopy: A promising and potential technique for the in vivo evaluation of vitiligo.

Fluorescence advanced videodermatoscopy (FAV) has been proposed recently to be a new, noninvasive method for in vivo skin examination at high magnification. The working principle underlying FAV relates to the ability of endogenous molecules to absorb specific wavelengths and emit fluorescence. Herein we report our experience with FAV in the study of active, non-segmental vitiligo treated with narrowband UVB. Our findings indicate that FAV has the potential for application in the clinical follow-up, disease prognosis, and therapeutic monitoring of vitiligo.
