Halo nevus

Last edited: 4/16/2026

Overview

Halo nevus, also known as halo naevus, is a benign melanocytic lesion characterized by a central, typically melanocytic, papule surrounded by a zone of peripheral depigmentation. The incidence in the general population is approximately 1% 1.

Diagnosis

  • Clinical appearance of a central pigmented lesion with a surrounding ring of depigmentation.
  • Dermoscopy may reveal characteristic features such as a central network and peripheral achromic halo.
  • Histopathology confirms the diagnosis, showing a central junctional melanocytic proliferation with surrounding dermal melanophages 1.

    • Management

  • No specific treatment is typically required as halo nevi are benign and self-limiting.
  • Removal may be considered for cosmetic reasons or if there is diagnostic uncertainty; options include surgical excision or laser therapy.
  • No specific drug classes or doses are recommended for treatment 1.

    • Special Populations

  • No specific information provided regarding pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1.

    • Key Recommendations

  • Halo nevi are benign and generally do not require treatment unless for cosmetic reasons or diagnostic uncertainty (Evidence: Expert opinion 1).
  • Histopathological examination is recommended when there is diagnostic doubt to confirm the benign nature of the lesion (Evidence: Expert opinion 1).
  • Monitoring is sufficient for most cases; active intervention is not routinely advised (Evidence: Expert opinion 1).
