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

摘要

Melanocytic nevi uncommonly develop halo-like phenomena. In this short review, we will discuss the major three types.Sutton nevus – more common in vitiligo – is characterized by loss of pigmentation around moles. Mimics of Suttonnevus have occasionally been reported in melanoma, although Sutton nevus itself is benign. Meyerson nevus is a pruriticlesion with a central mole surrounded by an eczematous halo. It is not necessarily associated with atopic dermatitis.The Wollina-Schaarschmidt phenomenon describes the halo-like skin free of psoriasis in patients with psoriasis.
