Abstract

Congenital melanocytic nevus is defined as a nevus present at birth or appearing within the first year of life and persistent throughout life. Congenital nevi are clinically larger than common nevi with color and shape variegation and tendency to become palpable and covered by terminal hair. The most frequent dermatoscopic pattern of congenital nevi of the head, neck, and trunk is the globular one (“cobblestone pattern”), while a reticulated or mixed pattern (reticular-globular) is especially detected on the extremities.
