BACKGROUND: Melanocytic nevi are frequently found on acral volar skin. Differentiation between nevi and melanoma is essential and sometimes difficult, although dermoscopy has enabled a more specific diagnosis of pigmented lesions. Dermoscopic patterns of lesions on acral volar skin have mostly been described in European and Asian populations. The Latin American population is heterogeneous, and particularly so in the case of Uruguayans, who largely descend from 3 distinct populations.
OBJECTIVE: To describe dermoscopic patterns of acral melanocytic nevi and evaluate their applicability in a Latin American population in Uruguay.
PATIENTS AND METHODS: This was an observational, descriptive, cross-sectional study conducted by 2 dermatologists from 4 dermatology clinics in Uruguay. Uruguayan patients older than 18 years with acral melanocytic nevi were included. Digital dermoscopic images were captured and jointly analyzed by 2 investigators.
RESULTS: A total of 158 acral volar nevi in 80 patients were analyzed. The most-prevalent pattern was the parallel furrow pattern (51.3% of nevi), followed by the latticelike pattern (13.3%), the homogeneous pattern (12.7%), the globular pattern (9.5%), the fibrillar pattern (7%), the globulostreaklike pattern (3.8%), and the nontypical pattern (2.5%). The reticular and transition patterns were not observed in our population.
CONCLUSIONS: The parallel furrow pattern, followed by the latticelike and homogeneous patterns, was the most-prevalent pattern in acral melanocytic nevi in the Uruguayan population. The fibrillar pattern was found exclusively on the soles. No new dermoscopic patterns were observed. The patterns described in Asian and European literature apply to our population.
