Dermoscopic features of an acral melanocytic nevus located in the transition zone between glabrous and nonglabrous skin

In this nevus located on the side of a toe, a densely arranged, reticular or branched pigmentation is observed (inset: clinical photograph). Note that the histopathologic features of melanocytic nevi located on the transition zone between glabrous and nonglabrous skin often mimic those of melanoma, showing prominent proliferation of solitary melanocytes within the epidermis. These histopathologic features may account for the unusual dermoscopic features of the nevi located on the transitional zone.
