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 are...
متن کاملDevelopment of Halo Nevus Around Nevus Spilus as a Central Nevus, and the Concurrent Vitiligo.
Halo nevus is a benign melanocytic nevus that is surrounded by a hypopigmented zone. The most frequent association with halo nevus is vitiligo, and this also appears in nearby regions, as well as at other remote sites. Although the mechanism for developing the depigmentation around nevus spilus is uncertain an immunologic process may be responsible for the finding of inflammatory infiltrates of...

متن کاملPigmented Skin Lesions in Children (Melanocytic Nevus, Clonal Nevus and Halo Nevus) — Symptoms and Treatment
Benign pigmented skin lesions are very common in children and can be generally classified into congenital or acquired nevi. Congenital nevi can be small, medium or large. Large nevi are usually associated with a higher risk of malignant transformation into melanoma. Acquired melanocytic nevi can be classified into typical melanocytic nevi, clonal nevi, or halo nevi. Cytological atypia can be ob...
متن کاملUltrastructural evidence for destruction in the halo nevus.
Nine halo nevi in various stages of regression were examined by electron microscopy for fine structural evidence of an immunological mechanism of tumor cell destruction and halo formation. Early regressing lesions (Stage I) showed nevus cells associated with infiltrating lymphocytes, monocytes, and plasma cells, but without nevus cell destruction. In later lesions (Stages II and III), vacuolar ...
