Abstract
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%). CONCLUSION The dermoscopic patterns of CAMNs and AAMNs differed markedly. In terms of dermoscopic patterns, CAMNs resembled acral melanoma more often than AAMNs did.

Abstract
BACKGROUND Dermoscopic screening facilitates early detection of melanoma and is recommended in patients with multiple or atypical nevi. OBJECTIVES To investigate whether dermoscopic features of acquired melanocytic nevi differ between six body sites (neck, axilla, pectoral area, shoulders, buttocks, legs) and the trunk. METHODS AND MATERIALS One hundred six patients with atypical nevi syndrome from a Digital Dermoscopy Unit were evaluated for the presence of nevi in each of seven body sites, and nevi representative of each region were selected as the predominant nevi. Dermoscopic features of 684 melanocytic nevi located in seven different body sites were analyzed. RESULTS Globular and globular-homogeneous pattern nevi showed a cephalad distribution. Nevi at the neck, axilla, shoulders, and pectoral area showed a higher proportion of globular and globular-homogeneous patterns than other locations (p < .001). Comma vessels were also more frequent on the neck, axillary area, and shoulders (p < .001). A reticular pattern was more frequent on caudal areas (legs, buttocks and lower back, and abdomen; p < .001). CONCLUSIONS Dermoscopic differences were found in different body areas. This information should be considered in the evaluation of lesions in patients with atypical nevus syndrome.
