Halo Nevus (Mole) - Realonomics (2022)

Halo Nevus (Mole)

A halo nevus is a mole surrounded by a white ring or halo. These moles are almost always benign, meaning they aren’t cancerous. Halo nevi (the plural of nevus) are sometimes called Sutton nevi or leukoderma acquisitum centrifugum. They’re fairly common in both children and young adults.

Should halo moles be removed?

Because halo nevi can also rarely be a sign of melanoma elsewhere on the body, most dermatologists will recommend a skin exam screening to look for melanoma elsewhere (even though it may be rare). Generally, a halo nevus does not have to be removed unless it has atypical features.

Is halo mole vitiligo?

Halo nevus (HN) has been shown to be associated with vitiligo, but no standard signs are currently available to identify HN patients at risk of vitiligo, and the relevant data obtained in previous studies are somewhat conflicting.

Crusting or scabbing can be a melanoma indicator. A scabbing mole may be especially worrisome if it also bleeds or is painful. So can other changes, including size, shape, color, or itching. Melanomas can scab because the cancer cells create changes in the structure and function of otherwise healthy cells.
