Malignant Melanoma Arising With Two Halo Nevi

Abstract

<h3>To the Editor.—</h3> This case is reported because of the recent awareness of the association of malignant melanoma with the halo nevus and the increasing investigative work in trying to understand the relationship. <h3>Report of a Case.—</h3> A 28-year-old blond woman was seen recently with a pink, raised tumor with a wide peripheral area of depigmentation on the middle of the upper back, a typical halo nevus that had been noticed for only a few months (Fig 1). This was removed surgically, and the histological examination proved it to be a malignant melanoma (Fig 2 through 4). The patient was then referred to a general surgeon specializing in melanomas who did a wider and deeper excision. The pathological report of the surgical specimen showed no residual melanoma. <h3>Comment.—</h3> The halo nevus is distinctive: a pigmented nevus becomes surrounded by a halo of depigmented skin, then gradually diminishes
