Moles and other birthmarks are pigmented spots or patches of skin that range in color from tan, brown and black (moles) to red, pink or purple (vascular nevi, such as strawberry hemangiomas or port wine stains). Some birthmarks appear shortly after birth, and others appear in childhood. Though most birthmarks are harmless, there are some that can be abnormal and it is important to have your child’s skin examined to make sure all moles are benign. Another advantage to having a skin check is that there can be an ongoing record of any change that may develop. Depending on their depth, location and color, as well as the patient’s skin type, age and other factors, treatment for benign birthmarks is available.
