Dermoscopy of a Spark’s nevus

Spark’s nevus is a particular type of melanocytic nevus that on histology shows features of both Spitz’s and Clark’s nevus. Clinically, it is an asymmetric, irregular, multicolored, pigmented lesion that is not clearly distinguishable from melanoma or dysplastic (Clark’s) nevus. Dermoscopic features have not been described yet, and one could speculate that they are similar to those of Clark’s nevi because the histopathologic architecture of Spark’s nevus is similar to that of a Clark’s nevus, resembling Spitz’s nevi in the epithelioid morphology of melanocytes. We present a 32-year-old woman with a Spark’s nevus, who upon dermoscopy showed a pronounced atypical network with accentuation of the blue veil and mostly peripheral dots.
