Here is a section regarding management:

Medical Care: Halo nevi are benign, and no treatment is necessary.

Consultations: The chief diagnostic consideration in patients with halo nevi is melanoma that is undergoing regression, although making this distinction is not usually difficult. Primary melanoma is usually solitary, whereas halo nevi are commonly multiple. Furthermore, children are affected more commonly with halo nevi; adults are affected far more commonly by melanoma.
