HALO NEVUS

By Gary M. White, MD

Halo Nevus This mole is almost gone, leaving just the halo.


The halo nevus is a mole surrounded by a white oval or circle. The white halo results from the immune system attacking and removing melanin from the mole and the surrounding skin.

Clinical

A completely depigmented circle of skin centered around a pigmented lesion in a child is typical. Multiple lesions are common. This author has had one patient with 35 halo nevi at one time!! Halo giant congenital nevi may occur [JAAD 1988;19:954–960].

Treatment

A complete skin examination should be done for all patients.

It is always important to evaluate the central mole for signs of atypia, e.g. using the ABCD's as with any other mole. If the central lesion is clinically atypical, it should be removed. In children however, most are benign and no treatment is needed. In contrast, most halo nevi in older adults should be removed as the possibility of melanoma is more likely.
