Verma V, Kar S. Halo Nevus. J Mahatma Gandhi Inst Med Sci 2019;24:53
A 10-year-old female child came with black colored dome-shaped lesion surrounded by the white area over the left ear. This black colored lesion was present since birth. After a few weeks of birth, this lesion increasing in size and slowly being surrounded by depigmented area. There was no history of any other white lesion all over body. There was no family history suggestive of vitiligo. There was no any other systemic and cutaneous abnormality. On cutaneous examination, hyperpigmented dome-shaped nodule surrounded by depigmented area over the tragus of the left ear was seen [Figure 1]. Clinical features and cutaneous examination were suggestive of halo nevus.

Halo nevus is also known as “Leukoderma acquisitum centrifugum,” “Perinevoid vitiligo,” “Perinevoid leukoderma,” “Sutton nevus,” and “leukopigmentary nevus.” Halo nevus designates the development of a halo of hypomelanosis around a central nevus. This is usually a benign melanocytic nevus, but rarely in cases of melanoma, nevi with various degrees of atypia, nonmelanocytic tumor and in inflammatory lesions halo phenomenon may be seen. Halo nevus is the result of the immunological response of the host to a nevus. This is more commonly seen in children or young adults of either sex, particularly on the trunk, less commonly on the head and rarely on the limbs. It occurs with increased frequency in patients with vitiligo. Normally, no treatment is required in case of halo nevus. The nevus has a tendency to get flatten and may disappear completely. The depigmented areas often persist, but it may repigment after a variable period of time.
