Halo nevus is a mole that is surrounded by a depigmented ring or 'halo'.
For reasons which are unknown, the body selects a particular mole or moles for destruction. This is presumably because the mole is recognized as being abnormal in some way. It is considered an autoimmune process.
The white skin of a halo nevus will burn particularly easily in the sun because it is missing protective melanin pigment.
The mole in the center of a halo is rarely malignant (cancerous) although all halo moles need to be examined carefully by an appropriate medical practitioner. A malignant mole is called a melanoma, and these may sometimes develop white halos around them as well.
Sometimes halo moles are triggered by sunburn which damages the mole and causes it to be recognized by the body as foreign.
