Sensitivity and Specificity Analysis of Different Lesion Areas of Vitiligo by Reflectance Confocal Microscopy

The results of RCM of different lesion areas of vitiligo showed that the rate of missed diagnosis of the progressive stage was lowest in the center of the lesion and comparable to that of multiple sites. The misdiagnosis rate for the stable stage was lowest in the perilesional normal skin, significantly differing from the other sites. Overall, scanning multiple sites yielded the most accurate results, offering flexibility in selection according to the patient's compliance.
