Most skin bumps, spots, growths, and moles are harmless. Colored skin spots, also called pigmented lesions (such as freckles, moles, or flesh-colored skin spots). or growths (such as warts or skin tags) may be present at birth or develop as the skin ages.
Most skin spots on babies will go away without treatment within a few months. Birthmarks are colored marks on the skin that are present at birth or develop shortly after birth. They can be many different sizes, shapes, and colors, including brown, tan, black, blue, pink, white, red, or purple. Some birthmarks appear on the surface of the skin, some are raised above the surface of the skin, and some occur under the skin. Most birthmarks are harmless and do not need treatment. Many birthmarks change, grow, shrink, or disappear. There are many types of birthmarks, and some are more common than others. For more information, see the topic Birthmarks.
Definition
Liver spots are flat brown-black spots that usually occur in sun-exposed areas of the body. They are also called age spots. They are unrelated to the liver or liver function. Lentigines, also known as sun spots, age spots or liver spots, are harmless, flat, brown discolorations of the skin which usually occur on the back of the hands, neck and face of people older than 40 years of age. These spots more than anything else, give away a person's age. Lentigines are caused by the skin being exposed to the sun over many years. If you do not believe that these brown, ugly marks on the back of your hands and face are caused by sunlight, look at the skin on your inner thigh. You will see that the skin of the inner thigh is completely devoid of age spots. Sun spots are harmless and do not need to be treated unless they are changing or getting bigger than the surrounding sun spots.
Causes, & Risk Factors
Liver spots are changes in skin color associated with older skin. The increased pigmentation may be brought on by aging, exposure to sun or other forms of ultraviolet light, or other unknown causes.
Liver spots are extremely common after 40 years old. They occur most often on the backs of the hands, on the forearms, shoulder, face, and forehead. These are the areas of highest sun exposure.
They are harmless and painless, but they may affect the cosmetic appearance. Occasionally, liver spots may mask the diagnosis of skin cancers.
Prevention:
The only way to prevent age spots is to use liberal amounts of sunscreen before the age of forty, avoid the sun, and wear protective clothing. These measures will also help prevent the formation of skin cancer and wrinkles.
Treatment:
The newest treatment for lentigines is alpha hydroxy acid gel and beta hydroxy acid gel. The lotion or cream is applied to the spots each night and in the morning.
Topical vitamin C treatment is effective for treating sun spots. Topical vitamin C works well when used in combination with alpha hydroxyacids.
Another treatment for lentigines is Retin-A. Retin-A cream is applied to the spots once a day for six months. This will cause lightening of large age spots and will make small ones disappear. Retin-A cream can be used in combination with alpha hydroxyacid.
Lentigines can also be treated with an alpha hydroxyacid peel. This involves applying a mild acid to the skin and then allowing the skin to heal. Chemical peels work best in people with blue eyes and light hair, but can be effective in all skin types. This is the second fastest way to get rid of age spots.
Liquid nitrogen therapy is the quickest way to get rid of lentigines. Liquid nitrogen is air that is so cold that it is in liquid form (-321ºF). The health care provider sprays the liquid nitrogen onto the age spot and this causes the mark to turn white a month or so after treatment. When liquid nitrogen is sprayed onto the skin, it can sting and may cause a permanent white spot or scar.
Cause of skin changes
Acne is a common skin change that occurs during the teen years and may last into adulthood. Acne may be mild, with just a few blackheads (comedones), or severe, with large and painful pimples deep under the skin (cystic lesions). It may be present on the chest and back as well as on the face and neck. Boys often have more severe outbreaks of acne than girls. Many girls have acne before their periods that occurs because of changes in hormone levels. For more information, see the topic Acne Vulgaris.
During pregnancy, dark patches may develop on a woman's face. This is known as the "mask of pregnancy," or chloasma, and it usually fades after delivery. The cause of chloasma is not totally understood, although it is thought that increased levels of pregnancy hormones cause the pigment-producing cells in the skin (melanocytes) to produce more pigment. You can reduce skin pigment changes during pregnancy by using sunscreen and staying out of the sun.
Actinic keratosis is a type of colored skin spot that is caused by too much sun exposure. Although it is not a skin cancer, it may mean that you have an increased chance of getting skin cancer, such as squamous cell skin cancer.
You may have an allergic reaction to a medicine that causes a skin change, or develop a skin reaction when you are out in the sun while you are taking a medicine (this is called photosensitivity). Rashes, hives, and itching may develop, and in some cases may spread to areas of your skin that were not exposed to the sun (photoallergy). For more information, see the topic Allergic Reaction.

Skin changes can also be caused by:

·
|
Autoimmune diseases, such as lupus and scleroderma.
|
|
·
|
Reactions to insect bites, such as Lyme disease. For more information, see the topic Lyme Disease.

|
Bacterial skin infections, such as impetigo and cellulitis.
|

|
Viral infections, such as chickenpox and shingles.

·
|
Liver problems, such as hepatitis, which may cause your skin and the whites of your eye to turn yellow (jaundice).

Common skin changes
Some common skin growths include:
Moles. Most people have between 10 and 40 moles. You may continue to form new moles until you are in your 40s. Moles may change over time. They can gradually get bigger, develop a hair, become more raised, get lighter in color, fade away, or fall off.
Skin tags are harmless growths that appear in the skin folds on the neck, under the arms, under the breasts, or in the groin. They begin as small fleshy brown spots and may grow a small stalk. Skin tags never turn into skin cancer.
Seborrheic keratoses are harmless skin growths that are found most often on the chest or back, occasionally on the scalp, face, or neck, and are less common below the waist. They begin as slightly raised tan spots that develop a crusty appearance like that of a wart. Seborrheic keratoses never turn into skin cancer. For more information, see the topic Seborrheic Keratosis.
Treatment of a skin change depends on what is causing the skin change and what other symptoms you are having. Moles, skin tags, and other growths can be removed if they become irritated, bleed, or cause embarrassment.
Skin cancer
While most skin changes are normal and occur with aging, some may be caused by cancer. Skin cancer may start as a growth or mole, a change in a growth or mole, a sore that does not heal, or irritation of the skin. It is the most common form of cancer in North America.
Skin cancer destroys skin cells and tissues and can spread (metastasize) to other parts of the body. The three most common types of skin cancer are basal cell cancer, squamous cell cancer, and melanoma. See an illustration of the ABCDs of melanoma .
Causes of skin cancer include:
|
·
|
Overexposure to the sun, such as a severe, blistering sunburn during childhood.
|
|
·
|
Years of overexposure to the sun as an adult.
|
|
·
|
The use of tanning beds or sunlamps. UV rays from a tanning bed may actually be more harmful than the sun because they are more intense.
|
|
·
|
Repeated exposure to X-rays, chemicals, and radioactive substances.
|
|
·
|
Radiation treatments for conditions such as eczema, psoriasis, or acne.

Kaposi's sarcoma is a serious form of skin cancer. It is often found in people who have an impaired immune system, such as people with AIDS. Blue-red raised bumps (nodules) may appear on the face, arms, and trunk and inside the mouth.
Early detection and treatment of skin cancer can help prevent problems. Treatment depends on the type and location of the growth and how advanced it is when it is diagnosed. Surgery to remove the growth will help determine what treatment will be needed.
