title: Homogeneous blue pattern in an acral congenital melanocytic nevus.
abstract: Dermoscopy in acquired acral melanocytic nevi has been widely studied. This is in contrast with the little information about the dermoscopic characteristics in congenital acral melanocytic nevi. We report a 46-year-old man who was referred due to a lesion on his right sole present since childhood corresponding to an acral congenital nevus. Dermoscopy showed a homogeneous blue pattern not previously described in acral benign tumors. The homogeneous blue pattern has previously been associated with blue nevus and skin metastasis of melanoma. The recognition of this pattern in benign acral congenital nevi is relevant in the clinical decision making concerning acral tumors.
