- Abstract
Background and Design: Compared to nevi in other regions, acral melanocytic nevi have special dermoscopic features due to their anatomical localizations. It may be difficult to distinguish the melanocytic nevi in these regions from early acral melanoma. For this reason, it is important to know the dermoscopic patterns of acral melanocytic nevi. Our aim was to evaluate the dermoscopic patterns and distribution features of acral melanocytic nevi. Material and Method: One hundred ninety-six acquired acral melanocytic nevi of 131 patients were evaluated retrospectively in this study. The demographic features such as age and sex, localization and pattern of nevi were recorded. Results: Of the 131 patients, 77 (58.7%) were female and 54 (41.3%) were male. Of all nevi, 92 (46.9%) were present on the palms, 104 (53.1%) were present on the soles. The localizations of acral nevi were as follows: inner arch (20%), finger (18.4%), hypothenar (12.8%), middle region (12.8%), thenar (11.7%), outer arch (10.2%), metatarsal region (8.7%) and heel (5.6%). The most common dermoscopic pattern was parallel furrow pattern (40.8%). The other patterns seen were homogeneous (15.8%), latticelike (11.7%), fibrillar (9.7%), globular (9.7%), reticular (5.6%), nontypical (3.6%), the pattern suggestive of malignancy (2.0%) and transition pattern (1%). Parallel furrow pattern, fibrillar and homogenous patterns were significantly more frequent on fingers, inner arch and outer arch, given in decreasing order (p<0.01, p<0.01, p=0.02, respectively). The four lesions suggestive of malignancy (2.0%) were excised and diagnosed as compound nevus, dermal nevus, dysplastic nevus and malignant melanoma. Conclusion: The three most frequently observed patterns were parallel furrow, homogenous and latticelike patterns, in decreasing order. The nevi were most frequently located on the inner arch. Parallel furrow pattern was mostly located on the fingers, fibrillar pattern and homogenous pattern were mostly seen on the outer and inner arches, in decreasing order of frequency.
