Synopsis

Halo nevus is also known as Sutton's nevus or perinevoid vitiligo. Halo nevi are benign melanocytic nevi surrounded by a peripheral rim of depigmentation. The depigmented ring is believed to be due to a secondary localized immune response to regional melanocytes. Clinically, halo nevi are characterized by a circular area of depigmented skin surrounding a central nevus of hyperpigmented skin. They are most often seen in teenagers. The pigmented nevus may eventually involute completely, leaving only the patch of depigmentation.

For more information, see OMIM.
