Disseminated Nonsegmental Vitiligo Associated With Halo Nevi and Premature Gray Hair

The document reported a rare triad involving rapid-onset halo nevi (HN), nonsegmental vitiligo, and premature hair graying (PHG) of scalp hair. HN are melanocytic nevi surrounded by a depigmented patch and are often linked with vitiligo. They can also be associated with various types of melanoma and may cause localized leukotrichia of terminal hair over the nevus. This case highlighted the unusual combination of these conditions occurring together.
