Abstract
Dermatology for pediatric skin of color is the application of dermatology to the genetically diverse and distinctive segment of the pediatric population that includes children of non-White racial and ethnic groups with increased pigmentation including individuals of Asian, Hispanic/LatinX, African, Native American, Pacific Island descent, indigenous people among others with overlap in particular individuals, and mixtures thereof. The discipline of pediatric skin of color can be challenging with difficulty in diagnosis of common conditions due to underlying pigmentation, variations in common hair styling practices, and differences in demographics of cutaneous disease. Whereas some conditions are more common in children of color, other conditions have nuances in clinical appearance and therapeutics with regard to skin color. This article, the second of the series, focuses on inflammatory skin disease nuances, melanocytic disorders, and hypopigmented mycosis fungoides.

Abstract
BACKGROUND/OBJECTIVE There are limited data on the dermoscopic characteristics of acral nevi in the population under 18 years old. Our aim was to determine the frequency of acral volar nevi in children and adolescents, characterize their dermoscopic patterns, and identify relationships with age and location. METHODS We prospectively examined the palms and soles of 1319 patients presenting to our outpatient clinic from July 2018 to April 2019. RESULTS Acral volar nevi were observed in 28% of the children and adolescent population included in the study. A total of 474 nevi from 365 patients were examined. The presence of nevi increased with age. The most common dermoscopic pattern was parallel pigmented furrows, detected in 57.8% of nevi. The other patterns observed were combination (14.1%), fibrillar (10.1%), and latticelike (8.8%). The parallel furrow and globulostreak-like patterns were more common on the palms, whereas the fibrillar and combination patterns were more frequently seen on the plantar surfaces. While the frequency of the parallel pigmented furrow pattern did not differ between the 0- to 12-year and 13- to 18-year age-groups, the dotted variants of the parallel furrow were observed more frequently in the 0- to 12-year-olds (58.2%) than in the 13- to 18-year-olds (41.7%). A combination pattern and its most common variant, parallel furrow + crista dotted pattern, were detected at a significantly higher rate in the 0- to 12-year group (22.1% and 16.3%, respectively) compared to the 13- to 18-year group (11.4% and 6%, respectively). CONCLUSIONS Acral melanocytic nevi are common in children and adolescents, and their dermoscopic patterns may be associated with anatomic localization and age.

Juvenile melanocytic acral nevus: A comparative study between MANIAC and non-MANIAC nevus and its clinicopathological characteristics. J Cutan Pathol 2019; 46:898-904.

Abstract
BACKGROUND Melanocytic acral nevi have a series of distinguishing features, including their location, patient age at onset, clinical progression, and histological findings. In particular, histopathological analysis often reveals a melanocytic acral nevus with intraepidermal ascent of cells (MANIAC nevus), which in some cases can be mistaken for atypia or malignancy. AIM This study describes the clinicopathological characteristics of acral nevi in patients under 18 years old and contrasts the clinical and histological features between MANIAC vs non-MANIAC nevi. METHODS This was a retrospective observational study, performed in our department in the decade between January 2007 and January 2017. We included patients younger than 18 years of age who were subjected to the removal of melanocytic acral nevi. RESULTS A total of 70 patients were studied. 54.2% (38/70) were females and 45.8% (32/70) were males. With regard to the type of nevus, 34 were compound, 27 were junctional, and 9 were predominantly intradermal lesions. We identified a total of 41 MANIAC nevi and 29 non-MANIAC nevi. Statistically significant differences between these two groups were identified in nevus size (larger in MANIAC) and the frequency of compound nevi (higher in the MANIAC group), but not in the remainder of the histological parameters studied.

Abstract
We report a case of acral pigmented lesions due to pine tar, a common compound used on baseball bats to improve grip, deposition. The patient presented with an acute concern for a new melanocytic lesion, and dermoscopy revealed large brown globules, not typical of melanocytic neoplasms. We propose that the coupling of dermoscopy and a thorough clinical history of exogenous exposures in similar clinical presentations can provide reassurance in evaluating atypical appearing pigmented lesions.

Abstract
BACKGROUND Dermoscopy is a useful tool for earlier diagnosis and differentiating benign lesions from melanoma. OBJECTIVES We aim to investigate dermoscopic features of acral nevi, age, and localisation-related findings of these lesions. METHODS This was an observational, descriptive study. Patients were retrospectively collected from the Department of Dermatology. The patients with acral nevi were included in the study. Inclusion criteria were Turkish nationality and the presence of at least 1 acral nevus diagnosed both clinically and dermoscopically. Lesions in dorsal and subungual areas were excluded. All nevi were examined by the same dermatologist. RESULTS The most common dermoscopic patterns were as follows: parallel furrow (87 patients; 41.4%), globular (24 patients; 11.4%), fibrillar (22 patients; 10.5%), combination patterns (19 patients; 9.1%), globulostreak-like (16 patients; 7.6%), lattice-like (15 patients; 7.1%), homogeneous (12 patients; 5.7%), nontypical (8 patients; 3.8%), parallel ridge (4 patients; 1.9%), reticular (2 patients; 1.0%), and crista dotted pattern (1 patient; 0.5%). The parallel furrow pattern was the most common pattern in all localisations. The number of parallel furrow patterns (5 lesions) was equal to the globulostreak-like pattern (5 lesions) on the thenar area. The number of parallel furrow patterns (4 lesions) was equal to the fibrillar pattern (4 lesions) on the heel. Parallel furrow (dotted variants) (11 lesions) and globulostreak-like patterns (5 lesions) were the most common patterns in the pediatric population (0-15 years old). The fibrillar pattern showed a tendency for soles (12 lesions), while a lattice-like pattern was seen more often in the plantar arch (3 lesions). CONCLUSIONS Description of the dermoscopic features of acral nevi is important to improve management and reduce the number of unnecessary excisions. The most common patterns were parallel furrow, globular, and fibrillar in our study. Parallel furrow (dotted variants) and globulostreak-like patterns were the most common patterns in the pediatric population. The fibrillar pattern showed a tendency for soles, while a lattice-like pattern was seen more often on the plantar arch. Therefore, there may be a relation between anatomic localisation, age, and dermoscopic pattern.

Abstract
Melanocytic lesions of acral sites are common, with an estimated prevalence of 28-36% in the USA. While the majority of these lesions are benign, differentiation from acral melanoma (AM) is often challenging. AM is a unique subtype of melanoma, with distinct molecular characteristics that are thought to contribute to its high rate of locoregional recurrence and worse prognosis. The advent of dermoscopy has since improved the diagnostic accuracy of AM, resulting in earlier detection and arguably improved survival. Additionally, the identification of unique genomic amplifications in AM invites the potential for future AM-specific targeted therapies. Herein, we discuss the importance of dermoscopy in the diagnosis of acral melanocytic lesions and review the treatment strategies for AM.

Abstract
Distinguishing benign acral nevi from small early acral melanomas may be challenging in certain cases. Dermoscopy is a noninvasive imaging technique that can help clinicians better visualize deeper lesion structures and thus more easily differentiate benign nevi from melanoma. We report the case of a 13-year-old girl with a changing dark brown to black macule with a central papular component on the volar surface of the right third finger. Dermoscopy revealed asymmetrically distributed irregular black blotches on a bluish-black background. Histopathology revealed a traumatized compound melanocytic nevus. Certain melanocytic nevi, although histologically benign, may not conform to the limited selection of reassuring benign dermoscopic patterns. Nevi in children are often dynamic and have a high likelihood of dermoscopic change.
