Dermoscopy of halo nevus in own observation

Abstract

IntroductionHalo 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.AimTo present the clinical and dermoscopic characteristics of halo nevus observed in dermoscopy.Material and methodsFifteen patients were diagnosed clinically and dermoscopically with halo nevus during planned routine dermoscopic examinations of all melanocytic lesions in 2007–2013. All digital images stored in the computer database were analyzed retrospectively according to the procedure described in the study. The clinical and dermoscopic parameters such as the dermoscopic pattern, color of nevus, special features and description of the surrounding halo were analyzed statistically.ResultsWe analyzed 22 halo nevi (9 in females, 13 in males) in 15 patients (7 females, 8 males) diagnosed during the dermoscopic examination. The mean age of patients during dermoscopic examinations was 18.2 years. Mean patients’ age at HN onset was 15.7 years. Halo nevi occurred the most often as a solitary lesion. The ratio of multiple halo nevi to solitary halo nevus was 5 : 10. Every third halo nevus was located on the posterior trunk upper. In 68.2% of HN cases, the surrounding rim (halo) was characterized by its homogenous, whitish color.ConclusionsDermoscopic patterns such as uniform globular and structureless constituted one-third each of them in all analyzed patterns.

Atypical Presentation of Halo Nevus over Eyelid with Poliosis

“…Dermoscopy of HN is characterized by the occurrence of the globular pattern with blue pepper-like granules and/or white-scar areas. [ 8 ] Our patient had similar findings. On histological examination, there is proliferation of melanocytes as nest and solitary units at the dermoepidermal junction and in the dermis toward the center of the lesion.…”

Current Challenges in Deciphering Sutton Nevi—Literature Review and Personal Experience

“…Of the 17 patients, 11 (64.7%) were women and six (35.3%) were men. The mean age at presentation was 26.05 years (median 29; range 9-50), somewhat higher than previous studies (18.2%; 22.4%) [15,16]. The most frequent Fitzpatrick skin phototype we found was type III (15/17; 88.22%), followed by type II (2/17; 11.8%).…”

“…The mean diameter of Sutton nevi for our group was 12.06 mm (range 5-19 mm). studies (18.2%; 22.4%) [15,16]. The most frequent Fitzpatrick skin phototype we found was type III (15/17; 88.22%), followed by type II (2/17; 11.8 %).…”

“…For 21 (65.6%) of them, we observed a symmetrical white rim ( Figure 1 a); for seven (21.9 %) an asymmetrical white rim ( Figure 1 b); whereas two (6.25%) had just a local white patch ( Figure 1 c) and two (6.25%) nevi lacked any halo or depigmented area ( Figure 1 d). A recent study described two other particular types of halo: one with visible telangiectasis and a pinkish surrounding halo [ 15 ]. The mean diameter of Sutton nevi for our group was 12.06 mm (range 5–19 mm).…”

Throwing light onto the core of a halo nevus: A new finding

“…Halo nevus (HN) is a rare finding characterized by a hypopigmented peripheral lining around the melanocytic nevus due to an autoimmune lymphocytic response which simulates a halo. In 1916, Sutton described HN as a “leukoderma acquisitum centrifugum.” Happle termed the entity as “Grünewald nevus.”[ 4 ]…”
