Can halo moles be cancerous?
Can halo moles be cancerous?
Can they be cancerous? Halo nevi are almost always benign. In rare cases, however, a halo nevus can indicate the presence of melanoma, a form of skin cancer, somewhere else on the body. This is more likely to be the case in older adults and those with halo nevi that are irregularly shaped or colored.
Is a 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. This study aimed to identify factors affecting the presence of vitiligo in HN patients.
How common are halo moles?
A halo nevus—”nevus” meaning mole or birthmark—is a fairly common skin lesion that is characterized by a white or de-pigmented ring around a colored spot. These lesions affect about 1% of the population and are considered benign.
Is halo nevus an autoimmune disease?
The etiology of halo nevi is unknown. It is an autoimmune response and T lymphocytes are considered to play a key role in the progressive destruction of nevus cells.
Should halo nevi be removed?
Background: Halo nevus (HN) is a rare dermatologic disorder characterized by typical whitish rim surrounding an existing melanocytic nevus resembling halo. It is a cosmetic problem that may be linked to vitiligo, and it is advised to remove these nevi in order to avoid development of vitiligo.
How long does a halo mole last?
Observations have showed that the halo nevi last for 10 years or more, but a large subgroup passes through various stages to finally regress completely. The process takes approximately 8 years on average.
Can halo nevus become vitiligo?
Why does my mole have a white head?
A pimple on a mole might feel raised and tender to touch. Pimples can form deep in the skin as nodules or cysts, or closer to the surface as whiteheads, blackheads, papules, or pustules. A pimple on a mole might have a black or white top, or ‘head,’ but the darker color of the mole might make this difficult to see.
Should halo moles be removed?
Risk of Skin Cancer 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.

Which subtype of nevus is most likely to develop a halo?
The answer is B: halo nevus. This is a benign lesion characterized by the appearance of a depigmented halo around a central melanocytic nevus. It is common in children and young adults, with a mean age at onset of 15 years, and it most often appears on the upper back.
