Birthmarks refer to skin spots that are apparent at birth or shortly afterward. In rare cases, some birthmarks may appear on the skin during childhood. Other types of marks on your skin such as moles may occur later on in life but aren’t considered birthmarks. Vascular birthmarks appear flat on the skin’s surface although in some instances, may be slightly raised. They may also change or evolve during the course of a person’s life. Colourations range from a light pink to a dark purple, and the markings vary in size.
Progression over time
It is thought there may be a reduced function of sebaceous (oil) and eccrine (sweat) glands, which may result in skin dryness and a heightened sensation of itch. Even at a young age, kids watch how their parents respond to such situations. This is where they learn how to cope with others' reactions. Talking simply and openly about a birthmark with kids makes them more likely to accept one as just another part of themselves, like hair color. A doctor should check a birthmark when it first appears to see what type it is, and to decide what monitoring or treatment it needs, if any.
How Common Are Birthmarks?
Keep in mind that surgery isn’t a guarantee against cancer. Fifty percent of melanomas found in people with giant congenital nevi occur elsewhere on the body. In addition, the estimated lifetime risk of melanoma for a person born with a giant nevus varies from 5 to 10 percent. This type of birthmark may occur at any time from birth through early childhood.

Another rare condition, Sturge-Weber syndrome, also appears as port-wine birthmarks along a specific branch of nerves and is caused by a different gene mutation. It also doesn’t run in families and can’t be inherited. Your doctor may suggest medicine or laser treatments for a hemangioma that is fast growing or threatens some aspect of a child's form or ability to function. If your child has more than one hemangioma, your doctor may want to check whether your child has internal hemangiomas. Port-wine stains may cause medical problems and emotional stress.

A healthcare provider will recommend the removal of certain birthmarks if you’re at a higher risk of developing skin cancer. Pigmented birthmarks also can pose an increased risk of skin cancer. A healthcare provider should check any changes that occur in the color, size or texture of a mole. See a provider right away if you have any pain, bleeding, itching or swelling of a birthmark. Birthmarks are common growths or lesions that appear on your skin at birth or shortly after birth.

In some instances, birthmarks may be removed for cosmetic reasons. Although a dysplastic nevus is often found on skin that’s been exposed to the sun, it can also appear in areas not exposed to the sun, including the scalp. When referring to a dysplastic nevus, your dermatologist might call it an atypical mole, as it looks different from a common mole.
What is the treatment for achromic naevus?
Call the doctor if a birthmark ever bleeds, hurts, itches, or gets infected. Like any injury where there is bleeding, clean the wound with soap and water and, using a gauze bandage, place firm pressure on the area until the bleeding stops. People with birthmarks should use a good quality sunscreen with an SPF of 30 or higher when outdoors in order to prevent complications. Many folk tales and myths exist about the causes of birthmarks, but none of these stories have been proven to explain the true causes of birthmarks. Treatment options depend on several factors, including the type, location, and severity of the birthmark.
Most people mean no harm, but it's also OK to let them know if they've gone too far. Large or prominent moles that affect appearance and self-esteem may be covered with special cosmetics. Some hemangiomas can cause problems if they bleed or press on important nearby structures, such as the eye or the upper airway.
Certain characteristics are specific to the different subtypes of these birthmarks. Colloquially, these are referred to as ‘red birthmarks’4. Some types of birthmarks appear more frequently than others. For example, vascular birthmarks like hemangiomas occur in 5 to 10 percent of newborns. A stork mark is another common type of vascular birthmark. Red birthmarks are colored, vascular (having to do with blood vessels) skin markings that develop before or shortly after birth.
Keep reading to find out the answers to these questions and more below. In most cases, no treatment is needed for the birthmarks themselves. When birthmarks do require treatment, however, that treatment varies based on the kind of birthmark and its related conditions. Achromic naevus is an uncommon birthmark (naevus) characterised by a well-defined pale patch. This is usually several centimetres in diameter, with an irregular but well-defined border. Often, smaller hypopigmented macules arise around the edges, resembling a splash of paint.
A congenital melanocytic naevus (American spelling nevus) is a proliferation of benign melanocytes that are present at birth or develop shortly after birth [1]. This form of a congenital naevus is also known as a brown birthmark. Hemangiomas grow quickly during the first 6 months or so of life, then usually shrink and disappear by the time a child is 5 to 10 years old. Some, particularly larger ones, may leave abnormal skin as this happens. Others may leave red pigmented skin, which can be helped with special laser treatment. Although they can be anywhere on the body, most hemangiomas are on the head or neck.
They can increase in size, a unique characteristic of these birthmarks. Growth rate is often quickest during a baby’s first few months of life (and up to 12 months)6. While further growth may occur beyond that, it is considerably slower, if at all. Generally, these marks remain at a fixed size for a period but may then reduce (in a process of involution and regression). While birthmarks can be a source of concern for new parents, they are usually harmless and do not require treatment.
