Halo Melanocytic Nevus

Halo nevi are common nevi exhibiting a peripheral vitiligo-like annulus or "halo" of hypopigmentation or depigmentation surrounding a central nevus (Fig. 4A). Histologically halo nevi demonstrate a dense lymphocytic infiltrate associated with the central nevus and a peripheral zone of hypo- to depigmentation of the epidermis, corresponding to the clinical halo (Fig. 4B). Halo melanocytic nevi may exhibit both clinically and histologically atypical features and thus raise concern for melanoma (Tables 4 and 7).

Synonyms: Suttton's nevus; leukoderma acquisitum centri-fugum.
