Congenital Nevus

Congenital nevi are strictly called congenital melanocytic nevi. They are brown or black moles which are present at birth, or which develop in the first month or so of life (brown birthmarks ).

Linear Epidermal Nevus

This is a type of birthmark that is usually present at birth, but may develop later in childhood. They are usually light or dark brown in color. They may start as a flat area in the shape of a line or as a “skin tag.” Over time, they grow and become thicker like a wart. They can be located anywhere on the body.
