How are moles formed? Why do we have moles on our skin? What are they for?

A mole or melanocytic naevus is a small, dark spot on the skin. It can be subdermal made of melanin, or a pigmented growth on the skin, formed mostly of melanocytes. The high concentration of melanin is responsible for their dark color. They are a member of the family of skin lesions known as naevi.





Moles may either be present at birth or develop later in life.





Acquired moles are a form of benign neoplasm, while congenital moles are considered a minor malformation, or hamartoma. Moles are most often of no medical consequence, but since they are permanent, they may occasionally be removed for cosmetic or other reasons.





Moles are usually circular or oval and not very large. Most children are born with moles, and almost everyone has at least one or two moles on their bodies. Large amounts can be concentrated on the back, the chest and arms.
