Reflectance confocal microscopy for the diagnosis of vulvar naevi: six cases

The differential diagnosis between vulvar naevi and melanoma is challenging. In vivo reflectance-mode confocal microscopy (RCM) is an emerging technique that allows non-invasive high-resolution imaging of the skin and mucosa. It has recently been used for the study of vulvar melanosis and melanoma, but it has not been so far employed for the diagnosis of genital naevi. The objective of this study is to evaluate RCM features of vulvar naevi and to compare them with dermoscopical and histopathological aspects.
