Atypical Presentation of Halo Nevus over Eyelid with Poliosis

Abstract

Halo nevus (HN) is benign skin condition with a central melanocytic nevus, surrounded by an area or halo of depigmentation. It is the result of immunological response of the body toward the nevus, which destroys the melanocytes in surrounding skin, leading to the depigmented halo. An increased frequency of HN in patients with vitiligo is observed. It is more commonly seen in children or young adults of either sex, particularly on the trunk, less commonly on the face, neck, and limbs. We present a rare case of HN which was present on the lower eyelid associated with poliosis, diagnosed with dermatoscopy.

Digital Dermoscopy, Reflectance Confocal Microscopy, and Pigmented Lesion Assay Gep for In-Vivo Monitoring of Multiple Halo Nevi on an Adult Patient

“…HNs are most frequently found on the trunk and multiple lesions are present in approximately half of all cases. Clinically, the width of the halo is variable but of uniform radial distance from the center nevus that presents as a tan, pink or brown uniformly colored round or oval macule [1]. In spite of the fact that most of the cases are idiopathic, sunburn or local skin trauma are suggested triggers that can lead to initiation of self-reactivity.…”
