What is a birthmark?
Any mark, spot, or bump that is present in or around the time of birth on the skin of an infant is a birthmark. Mothers are fond of giving these rather romantic names such as angel's kisses, stork bites, or beauty marks. Most of these lesions are not particularly esthetically desirable.
What are the different types of birthmarks?
Birthmarks can be categorized according to their composition. Marks as a result of excessive accumulation of melanin are called pigmented birthmarks since the great majority of them are brown to black. Other birthmarks appear lighter than the rest of the skin due to a relative lack of melanin.
Some birthmarks are composed of blood vessels and are called vascular birthmarks. They are generally red, blue, or purple. Other birthmarks are composed of lymphatic tissue (cystic hygroma), breast tissue, and epidermal tissue, which are often yellow to flesh-colored.
What is a Mongolian birthmark?
Pigmented birthmarks can be flat or elevated. They may simply be due to excessive deposition of melanin pigment in the deeper layers of the skin called dermal melanosis. This is particularly common in more heavily pigmented infants and is commonly called a Mongolian birthmark or spot. More frequently, there are accumulations of melanin produced by and contained in pigment cells called melanocytes. The medical term for such a concentration of melanin-producing cells is a nevus. These nevi are generally small, no larger than ¼ inch in diameter, however, they can be quite large, covering a significant portion of the infant's skin.
What are the characteristics of vascular birthmarks?
The color of vascular birthmarks ranges from light pink to dark purple, and they can be either flat or elevated. Their size is quite variable, as well. Certain types of vascular birthmarks can evolve and change after birth.
What is a strawberry birthmark?
A hemangioma is a type of vascular birthmark that is also called a strawberry mark, nevus vascularis, capillary hemangioma, or hemangioma simplex. A strawberry birthmark can appear on any part of the body. The most common areas of the body where you will find a hemangioma include the face, scalp, back, or chest.
The red color of the strawberry birthmark comes from the closely packed blood vessels where it is found. It is painless and the actual cause is not known.
A strawberry mark will typically appear at birth and may grow quickly. Oftentimes it will disappear from the child's skin by age 9.
What is a birthmark caused by?
Most birthmarks are probably due to defective migration of cells during fetal development. Once these cells start to multiply, they produce tissue with the characteristics of their cell type though they are not where those cells typically are located.
What disorders are associated with birthmarks?
Several rare serious disorders are associated with both pigmented (café au lait mark, for example) and vascular birthmarks. It would be appropriate that any infant with a birthmark is examined by a pediatrician to detect any of these uncommon conditions. Some of these disorders can be inherited, so affected families need to be educated as to their significance.
Can skin damage during delivery produce a birthmark?
Are any symptoms and signs associated with birthmarks?
Pigmented birthmarks, aside from their coloration, cause no symptoms. Vascular birthmarks of certain types can produce significant symptoms. The identification of the type of vascular birthmarks may be difficult and require certain advanced imaging techniques as well pathological examination of samples of the birthmark. Certain vascular birthmarks called hemangiomas can begin as flat lesions at birth but enlarge rapidly during the first few months of life. They may ulcerate and disappear slowly, leaving only a scar. If this type of lesion is situated adjacent to an important anatomical structure like an eye or mouth, it may need to be treated to hasten the natural resolution.
How do I remove birthmarks?
It is now possible to treat many kinds of both pigmented and vascular birthmarks. The approach depends on the type of tissue involved and the risks versus the benefits of treatment. The pediatrician is an excellent source of information as to potential treatment options.
Birthmark removal depends on the nature of the tissue involved. Medical treatment can hasten the resolution of certain kinds of vascular birthmarks. Generally, measures that destroy the involved cells of the birthmark are required for both pigmented and vascular birthmarks. Either scalpel surgery, lasers, and rarely radiation can be helpful.
Does insurance cover the cost of birthmark removal?
As with all such questions about insurance coverage, each company may be different. Most birthmarks that are small and not visually unpleasant are unlikely to require treatment and are rarely covered. Any birthmark that is likely to impair either the physical or mental health of the child is much more likely to be covered.
What is the prognosis of birthmarks?
A few small pigmented birthmarks are quite common and do not need to be treated. This is also true for vascular birthmarks. Smaller hemangiomas will disappear spontaneously, leaving a small insignificant scar depending on the sites involved. Dermal melanosis eventually fades.

DermabrasionDermabrasion is a skin procedure that freezes and then sands the skin. Dermabrasion improves the appearance of acne scarring and other skin conditions, such as wrinkles and skin lesions. Possible dermabrasion side effects include darkening of the skin, scarring, infection, and uneven changes in skin color.
EczemaEczema refers to skin inflammation. There are many different types of eczema that produce symptoms and signs that range from oozing blisters to crusty plaques of skin. Treatment varies depending upon the type of eczema the person has.
GlaucomaGlaucoma is a common eye condition in which the fluid pressure inside the eye rises because of slowed fluid drainage from the eye. If untreated, glaucoma may damage the optic nerve and other parts of the eye, causing the loss of vision or even blindness.
Itching (Pruritus)Itching can be a common problem. Itches can be localized or generalized. There are many causes of itching including infection (jock itch, vaginal itch), disease (hyperthyroidism, liver or kidney), reactions to drugs, and skin infestations (pubic or body lice). Treatment for itching varies depending on the cause of the itch.
Melanoma (Skin Cancer)Melanoma is a type of skin cancer which begins in skin cells called melanocytes and affects more than 53,600 people in the United States each year. These melanocytes can grow together to form benign moles which, after a change in size, shape, or color can be a sign of melanoma. Caused by sun exposure, early detection becomes extremely important to avoid a spread to other areas of the body. Diagnosis is confirmed through a biopsy of the abnormal skin and treatment depends on the extent and characteristics of the patient. Metastatic melanoma is melanoma that has spread to various organs.
Moles PictureMoles are growths on the skin that are usually brown or black. See a picture of Moles and learn more about the health topic.
Pernicious AnemiaPernicious anemia is a blood disorder in which the body does not make enough red blood cells due to a lack of vitamin B12 in the blood. Pernicious anemia can develop from a lack of a protein that helps the body absorb vitamin B12, not getting enough B12 in the diet, and certain intestinal conditions that interfere with the absorption of vitamin B12 such as Crohn's disease, celiac sprue, or ulcerative colitis. There is no cure for pernicious anemia, thus treatment is life-long.
SclerotherapyThe procedure to eliminate varicose veins and spider veins is called sclerotherapy. Generally, a salt solution is injected directly into the vein. The solution irritates the lining of the blood vessel, causing it to swell and stick together, and the blood to clot. After a period of time, the vessel turns into scar tissue that fades from view.
Skin Cancer (Nonmelanoma Skin Cancer or Keratinocyte Cancer)Skin cancers occur when skin cells undergo malignant transformations and grow into tumors. The most common types of skin cancer, basal cell carcinoma and squamous cell carcinoma, are highly curable when they are diagnosed and treated early. Sun exposure, tanning beds, depressed immune system, radiation exposure, and certain viral infections are risk factors for skin cancer. Skin cancers are treated with surgery or radiation. The prognosis of nonmelanoma skin cancers is generally very good.

Sunburn (Sun Poisoning)Sunburn is caused by overexposure to UV radiation from the sun. UV rays can also damage the eyes. Repeated overexposure to UV rays also increases the risk of scarring, freckles, wrinkles, and dry skin. Symptoms of sunburn include painful, red, tender, and hot skin. The skin may blister, swell, and peel. Sun poisoning (severe sunburn) includes nausea, fever, chills, rapid pulse, dizziness, and more. Home remedies can help relieve sunburn pain, blisters, and peeling. Severe sunburns may need medical treatment. Sun protection and sunscreen for a person's skin type are recommended to decrease the chance of severe sunburn and sun poisoning.
