This skin lesion is quite common in the population, and it can present at birth, known as a congenital meloncytic nevus, or later in life as an acquired nevus. Should the nevi appear in toddler- or school-aged children, they are more likely to remain present throughout the rest of that person's life. If they arise in adolescence and adulthood, the nevi most likely occur due to sun damage. With appropriate coverage from the sun, these lesions may go away over time. Also, lighter-skinned people tend to have nevi more frequently than dark-skinned people.
