Background The dermoscopic patterns of acral melanocytic nevi (AMNs) are crucial in differentiating them from acral melanoma. Several studies have reported the dermoscopic patterns of acquired acral melanocytic nevi (AAMNs). However, few have investigated the dermoscopic patterns of congenital acral melanocytic nevi (CAMNs). Objective To compare the clinical and dermoscopic features of CAMNs and AAMNs.Methods The present study included 43 patients with CAMNs and 40 with AAMNs. We reviewed their medical records as well as their clinical and dermoscopic findings.Results Congenital acral melanocytic nevis were more asymmetrical than AAMNs (P = 0.002) and presented more frequently as comma-shaped (P = 0.005). Regarding dermoscopic findings, globular pattern (55.8%) was the most common feature of CAMNs, while parallel furrow pattern (37.5%) was the most common feature of AAMNs. The presence of fibrillar, globular, and parallel ridge patterns, and diffuse multi-component pigmentation differed significantly between the groups (P < 0.05). Furthermore, CAMNs showed melanoma-specific dermoscopic patterns, such as parallel ridge (18.6%) and diffuse multi-component pigmentation (25.6%). ConclusionThe dermoscopic patterns of CAMNs and AAMNs differed markedly. In terms of dermoscopic patterns, CAMNs resembled acral melanoma more often than AAMNs did.

“…Minagawa et al reported a significant correlation between the frequency of dermoscopic patterns and age. 29 In their study, the fibrillar and "peas-in-a-pod" patterns (described in acral congenital nevi) were significantly prevalent in individuals under 20 years of age. The nontypical pattern was prevalent in the group over 59 years of age.…”

BackgroundPigmented lesions on acral sites are common; clinical differentiation of nevi and early melanoma can be challenging. In these cases, dermoscopy can provide a more accurate diagnosis. Most dermoscopic patterns on acral skin have been described in Asian and European populations, while there are few studies in Latin American populations.ObjectivesTo determine the frequency of pigmented lesions in volar skin and their dermoscopic patterns in a Mexican population. Methods: An observational, descriptive, cross-sectional study was performed in Hispanic patients with the presence of at least one pigmented lesion on acral skin. Clinical and dermoscopic images were obtained. These were subsequently evaluated independently by two dermatologists trained and experienced in dermoscopy.ResultsA total of 582 pigmented lesions on volar skin were diagnosed in 321 patients. Overall, prevalence of acral pigmented lesions on volar skin was 6.8%. For both observers, parallel furrows were the most frequent pattern described, but for observer 2, a lattice-like pattern was prevalent on the toes and a homogeneous pattern on the sides of the feet. There was lower inter-observer agreement, with a kappa index of 0.144.Study limitationsThe lesions were not biopsied, so clinical-histological correlation could not be performed. The study did not correlate dermoscopic patterns with age.Conclusions.As previously reported by other authors, parallel furrows were the most frequently found dermoscopic pattern on palmoplantar skin.

Age and Anatomical Location–Related Dermoscopic Patterns of 210 Acral Melanocytic Nevi in a Turkish Population

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.
