Halo nevus is a mole, red spot, or other small round skin blemish that is surrounded by a circle (halo) of lighter, depigmented skin.
It is rare for it to be cancerous so generally there is no treatment needed.
If the halo nevus doesn’t display any signs or symptoms of melanoma (skin cancer), it can be left alone. It may in time disappear on its own, but some people choose selectively to have it removed for cosmetic reasons.
There have been a few studies done to see if it is possible to modify the immune response that the halo nevus triggers. There have been limited studies with limited participants, so there have been no reliable conclusions drawn.
Choosing Treatment for Skin Lesions and Blemishes
When there is a skin lesion or blemish the first thing to do is to consult with a healthcare professional to determine if there is a health issue like cancer. One of the causes of a skin lesion is halo nevus. This type of lesion commonly has a mole in the middle and light or white area (depigmented skin) circling it. Before the conclusion is drawn that a halo nevus is developing a thorough examination of the area should be done.
A scrape that is healing can resemble a halo nevus because the new skin that is revealed as the scab regresses may be a lighter color than surrounding skin. This type of lesions will heal by itself within weeks; a halo nevus may never disappear. If there isn’t any health problems that are causing this type of mole, no treatment is necessary.
Though treatment is not usually needed, some people may choose to be part of a trial that offers the possibility of speeding up the disappearance of the blemish. Another option is elective cosmetic surgery. This treatment is commonly chosen when the lesion is in a highly visible area like on the face or hands. The risk of scarring should always be considered when having a halo nevus removed. In the case of cancer being suspected, it will be important to have a medical professional check the lesion and if, the results of testing show evidence of melanoma then treatment will no longer be elective.
Cancer Treatment for Halo Nevus
A halo nevus isn’t cancerous on their own, but they can become malignant, just like with any mole. These are the signs of skin cancer:
- Irregular edges on the mole
- Changes in appearance of the mole
- Bump or nodule on the skin
- Enlarged lymph nodes in the area
Cancer is diagnosed by doing a biopsy of the tissue that is suspected of having melanoma. Once the diagnose of cancer is confirmed, one or more of the following will happen.
- Biological therapy
If the melanoma has spread to the lymph nodes more aggressive treatment will be necessary. When the halo nevus is not cancerous, sometimes surgery is still performed.
Cosmetic Surgery to Remove Skin Blemish
All surgery and medical procedures come with some risks. It is recommended when there is a blemish or skin lesion like a halo nevus it is best to leave it be and just monitor it for signs of melanoma. For the ones on the face, scar makeup may be used to cover it. Ways to remove the halo nevus include some of the same treatments that are used to treat other skin lesions. Natural treatments include the following:
- Applying apple cider
- 5% iodine
- Slice of garlic
- Banana peel
- Baking soda and castor oil mixture
These remedies take longer than medical procedures, like surgical removal or laser treatment, but have less risk. They vary in effectiveness and may cause skin damage. They work by helping to lighten or remove the nevus but don’t do anything to re-pigment the skin around the mole. There are some medications that have been tested to stimulate the immune system to speed up the time that it takes the halo to overtake the nevus.
Treatment Trials for Skin Lesions With Depigmented Halo
MEDA AB, Graceway Pharmaceuticals, Mochida, and iNova Pharmaceuticals market imiquimod, which modifies the immune response. It is known by the following trade names:
There have been few studies done, and they resulted in a low rate of serious side effects but without reliable conclusions due to the lack testing on patients. The studies have been done at several institutions. More information can be found at Medify on study results and the institutions that were involved.
In a world where perfection is acquired through digital corrections and programs like Photoshop it is easy to believe that perfection is everyone’s goal. Some believe that individuals focus on flaws like moles and skin lesions like halo nevus but the truth is they often get very little attention by others, so there is no reason to treat it unless it is found to have cancer. It is much more beneficial to spend time and energy to develop an inner beauty that draws so much attention that it outshines any outward imperfections.
