Halo Nevus

Halo Nevus

Halo nevus (or Halo naevus, also known as leukoderma acquisitum centrifugum, Sutton's nevus or Sutton's Disease) is a mole that is surrounded by a depigmented ring or 'halo'.

Causes

Halo nevi are caused when white blood cells target a mole. The cause for the attack is unknown.

Predilection

Halo nevi are estimated to be present in approximately 1% of the general population, and are found to be more prevalent in people with vitiligo, malignant melanoma, or Turner syndrome. All races and sexes are equally susceptible to this disease, although a familial tendency has been reported. The average age of onset is 15 years.

Cancer

Halo nevi are entirely benign, and are of only cosmetic significance. However yearly exams by a dermatologist are recommended to ensure there are no other atypical moles or malignant melanoma.

Treatment

As halo nevi are only of cosmetic significance, no treatment is required, and patients will be asymptomatic.
