Melanocytic halo nevus
The melanocytic nevus is a well-defined nevus, in the form of a brown spot or a nodule surrounded by a white halo.
We usually find it in the trunk (upper back).
We find it more often in people with fair skin types. Children and adolescents have it more often than adults.
It may automatically decrease or progress (more often in children of vitiligo patients).
It may be directly related to vitiligo and metastatic melanoma. The prevalence rate of halo nevi in children is unknown. It could probably be 1%. However, Precic and his team observed that the halo nevi prevalence in children with vitiligo is between 2.5% and 34%.
