Association Between Halo Nevi and Melanoma in Adults

Journal of the American Academy of Dermatology

TAKE-HOME MESSAGE

• In this retrospective review, the charts of adult patients with a new diagnosis of halo nevi (HN) were reviewed to determine the rate of melanoma development within 1 year of when the HN diagnosis was made. In the 879 patient charts reviewed, 95 melanomas were found. Only 9 occurred within 1 year of HN development, which yielded a melanoma incidence rate in patients with HN diagnosis of 0.01 per person per year. The remaining 86 melanomas occurred either before the HN diagnosis or after a 1-year period. This study suggests that in an adult who develops new-onset HN, the risk of developing a cutaneous melanoma is as low as 1% per person per year. This risk is similar to that incurred by having multiple atypical nevi or a personal or family history of melanoma.

• The authors conclude that an annual skin cancer screening examination is adequate for screening for melanoma in these patients with new-onset HN.

Abstract

The halo nevus (HN) is thought to be of little concern in children. In adults, however, a new-onset HN has been suggested to be a harbinger of melanoma – either within the HN or at distant cutaneous or non-cutaneous sites – based on case reports and small case series.^1,2 Multiple widely-used dermatologic reference texts^3,4 and online references (such as UpToDate.com, DermNetNZ.org) advocate for extensive melanoma screening in adults with new-onset HN, including full cutaneous, oral, ophthalmic, and vaginal examinations, despite limited evidence supporting an association between HN and melanoma. We aimed to further investigate the association between new-onset HN and melanoma in adults by evaluating the incidence of melanoma in the year following a new HN diagnosis.
