216.5 – Benign neoplasm of skin of trunk except scrotumSynopsis
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.VisualDx also has information on the following topics:
