Halo nevus (also known as "Leukoderma acquisitum centrifugum," "Perinevoid vitiligo," and "Sutton nevus"[1]:689) is a mole that is surrounded by a depigmented ring or 'halo'.

Contents

Causes

Halo nevi are caused when white blood cells target a mole. The cause for the attack is unknown.[2]

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[2], or Turner syndrome[3]. 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 physician are recommended to ensure there are no other atypical moles or malignant melanoma[3].

Treatment

As halo nevi are only of cosmetic significance, no treatment is required[4], and patients will be asymptomatic.
