Homogeneous blue pattern: A rare presentation in an acral congenital melanocytic nevus

Acral melanocytic nevi are relatively frequent in the palmoplantar location. In congenital nevi various characteristic dermoscopic patterns have been described, such as reticular and globular patterns, brown pigmented areas, and areas with peripilar depigmentation. However, there are few reports on the dermoscopic pattern of acral congenital nevi. The homogeneous blue pattern is typical of blue nevus and is not typical of acral localization and metastasis of cutaneous melanoma. However, this pattern should be considered characteristic of acral congenital nevus.
