Whereas the dermoscopic features of other pigmented skin lesions have been extensively described, little is known about vulvar melanosis. The ringlike pattern was frequently combined with multifocality and simultaneous occurrence at the labia majora and the labia minora. In most cases, it develops on the labia minora, but it can also occur on the labia majora, perineum, introitus, vagina, and cervix. Although VM is a benign lesion, its correlation with mucosal melanoma is still under debate. It often poses a diagnostic challenge because it shows many clinical features consistent with those of melanoma.
