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'.
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 in a persons teenage years.
Treatment
As halo nevi are only of cosmetic significance, no treatment is required,[4] and patients will be asymptomatic. Although halo nevi are harmless, it is important to monitor the lesion on regular basis.[5] Watch out for any changes in appearance of existing or new halo nevi. If there is any change in appearance or is associated with pain, itch, and infection, a doctor should be consulted immediately to exclude the possibility of melanoma.
