Nevi presenting a halo: Sutton nevus, Meyerson nevus, and Wollina-Schaarschmidt halo-like dermatosis

The most common and well known is nevus Sutton or halo nevus first described in medical journals in 1916, where a hypopigmented area develops around a pre-existing melanocytic nevus. Halo nevi undergo specific sequelae: In Stage I the nevus remains brown, in stage II its pigment can disappear leading to a pink-colored papule. In stage III the central papule disappears, leading to a circular area of depigmentation. Eventually, in stage IV the depigmented area may show repigmentation [1]. The loss of color is the result of a cytotoxic T-cell attack against melanocytes and can lead to a complete disappearance of the mole [2]. Halo nevi are more common in vitiligo. About one quarter of children with vitiligo also have halo nevi [3].
