Halo nevus

Eric K W Wong, Muhammad N Mahmood, Thomas G Salopek
Congenital melanocytic nevi (CMNs) naturally evolve throughout life, growing proportionately with the child, darkening, and exhibiting textural or surface changes (e.g., papillomatous, verrucous, cerebriform), hypertrichosis, and, later in life, lightening of pigmentation. We report the case of a 5-year-old child with complete resolution of a medium-sized CMN involving the distal left leg and foot via sclerosis and in the absence of any halo phenomenon. Spontaneous regression of CMN via sclerosis is rare, and it is thought that an immunologic mechanism different from the mechanism that the halo phenomenon induces mediates this regression...

Meyerson phenomenon (MP) is characterized by a symmetrical area of erythema and scales encircling a central lesion, which is most commonly a banal melanocytic nevus. Herein, we describe an unusual case with MP representing an eczematized response to a melanoma in situ and review the literature covering this entity. A 56-year-old man presented with a 6-month history of a pruritic, pigmented lesion on the trunk. The patient had no other significant medical history and no notable family history of similar lesions...

BACKGROUND/OBJECTIVES: The association between vitiligo and congenital melanocytic nevi remains incompletely understood. The objective of this study was to investigate the frequency of depigmentation, including vitiligo, in patients with a large congenital melanocytic nevus (LCMN), which is a rare melanocytic tumor variant. METHODS: We retrospectively reviewed the files of 92 patients with an LCMN, including photographic documentation regarding the presence of pigment loss on the nevus mass, around the nevus, around the satellites, and elsewhere on the body...

Halo congenital melanocytic nevus (CMN) associated with vitiligo is rare, especially with regard to CMN excision. Only two reports of excision of halo CMN following repigmentation of vitiligo are found in the literature. We present a case of a girl with halo CMN and periorbital vitiligo. The halo CMN was excised and followed by spontaneous improvement of vitiligo. The result suggests excision of the inciting lesion may be a promising way to control vitiligo.

Congenital melanocytic nevus (CMN) is a neural crest-derived hamartoma, which appear at or soon after birth. CMN has a dynamic course and may show variable changes over time, including spontaneous involution. Spontaneous involution of CMN is a rare phenomenon and is often reported in association with halo phenomenon or vitiligo. The mechanism of halo phenomenon is yet to be investigated but is suggested to be a destruction of melanocytes by immune responses of cytotoxic T cells or IgM autoantibodies. Here, the authors report an interesting case of spontaneously regressed medium-sized CMN with halo phenomenon and without vitiligo, which provides evidence that cytotoxic T cells account for the halo formation and pigmentary regression of CMN...

BACKGROUND: Previous studies have characterized differences in vitiligo associated with halo nevi, but the features of vitiligo presenting with halo nevus in children have yet to be fully described. AIMS: We sought to provide an epidemiologic and clinical comparison of cases of childhood vitiligo presenting with or without associated halo nevi. MATERIALS AND METHODS: This was a retrospective chart review of children diagnosed with vitiligo in an academic pediatric dermatology practice from January 1990 to November 2014...

Halo (Sutton's) phenomenon has been described as a depigmented halo that is associated most commonly with acquired melanocytic nevi; but it may be associated with various types of melanocytic skin tumors, melanoma being the most concerning. Different authors have been preoccupied with elucidating morphological features of melanocytic tumors associated with a depigmented halo. We reviewed the literature and discussed the main features of melanocytic halo tumors regarding histopathological, immune microenvironment profile and dermatoscopic appearance...

Vitiligo is a refractory skin disease. To investigate the risk factors and treatment responses of patients with vitiligo in Japan, we recorded and analyzed the details of 713 vitiligo patients (comorbidity, treatment responses, family history, age, and sex) who visited the dermatology clinic of the Nagoya City University Hospital, Nagoya, Japan between January 2004 and August 2010 (mean age, 35.2 years; 302 men, 411 women) using logistic regression analysis. The results are expressed as odds ratios (OR) with 95% confidence interval (CI)...

The early detection of malignancy, particularly uveal melanoma, is crucial in protecting visual acuity, salvaging the eye, and preventing metastasis. Risk factors for early detection of uveal melanoma have been clearly delineated in the literature and allow identification of melanoma when it is tiny and simulates a nevus. These factors include thickness >2 mm, presence of subretinal fluid (SRF), symptoms, the orange pigment, margin near optic disc, acoustic hollowness, surrounding halo, and absence of drusen...

Halo phenomenon of nevus may be observed as a circular reaction, although it is unusual around tumors. A 29-year-old woman presented with a pigmented lesion on the cheek since three years. She noted whitening of the skin around the lesion almost after a year following its appearance. Dermatologic examination revealed a pigmented nodular lesion with a hypopigmented halo on the left infraorbital region. The clinical impression was halo nevus, whereas basal cell carcinoma (BCC) was considered in dermatoscopic differential diagnosis...

Melanoma of the eye can involve the uveal tract with iris, ciliary body, or choroid involvement or it can involve the conjunctiva, eyelid, or orbit. Uveal involvement with choroidal melanoma is the most common, found in light complexion Caucasians with an age-adjusted incidence of 4.3 per million persons. Early detection of uveal melanoma is critical. The ABCDEF guide helps to differentiate iris nevus from iris melanoma. The letters represent: A, age young (≤40 years); B, blood in anterior chamber; C, clock hour of mass inferiorly; D, diffuse configuration; E, ectropion; and F, feathery margins...

The pathogenesis and prognostic implications of regression in melanoma are not well understood. It has traditionally been considered an immunologically mediated phenomenon. Improvement in the knowledge of the mechanisms that lead to regression may prove to be of great value in an era in which treatments oriented to the augmentation of the host's immunity against melanoma have demonstrated excellent clinical results. This study was designed to improve the understanding of the mechanisms underlying melanoma regression and the differences between similar situations in benign melanocytic nevus...

BACKGROUND: Spitz naevi may present a wide spectrum of morphologies. Histopathologically, many variants, including desmoplastic, angiomatoid, verrucous/polypoid, plexiform, pagetoid, halo, myxoid, granulomatous and tubular Spitz naevi have been described. Clinical and dermoscopic features of these unusual variants of Spitz naevi have been reported only rarely. OBJECTIVES: The aim of this study is to describe clinical, dermoscopic and histopathological features of uncommon morphological variants of Spitz naevi in order to raise awareness among clinicians about their peculiar patterns of presentation...

A 68-year-old man presented with significant, asymptomatic, unilateral eyelash poliosis, not associated with any ophthalmic or systemic conditions. He reported that this started about 40 years ago with a few lashes in the central portion of his eyelid and that adjacent eyelashes subsequently became involved over the next 4 to 5 days. He had normal ophthalmologic and neurologic examinations with no other relevant medical history reported. The case might be an unusual presentation of a halo nevus. To the best of the authors' knowledge, this is the first such case reported regarding the eyelashes...

INTRODUCTION: Halo nevus (HN) is a rare dermatologic entity characterized by a typical whitish rim encircling the existing melanocytic nevus resembling a halo. The clinical picture is suggesting its diagnosis, but so far only several dermoscopic descriptions of halo nevus have existed in the PubMed database. AIM: To present the clinical and dermoscopic characteristics of halo nevus observed in dermoscopy. MATERIAL AND METHODS: Fifteen patients were diagnosed clinically and dermoscopically with halo nevus during planned routine dermoscopic examinations of all melanocytic lesions in 2007-2013...
