Dermatofibromas
|
Small, firm, red or brown scar-like bumps caused by a buildup of fibroblasts (soft tissue cells under the skin). They often happen on the legs and may itch. They often result from trauma, like a bug bite.
|
Dermatofibromas can be surgically removed if they become painful or itchy.
|
|
Dermoid cysts
|
A noncancerous (benign) tumor that is made up of hairs, sweat glands, and oil (sebaceous) glands. Some internal dermoid tumors may even contain cartilage, bone fragments, and teeth. These are rare and are usually present at birth.
|
Dermoid cysts may be surgically removed for cosmetic reasons or if they are causing a problem, such as on an eyelid.
|
|
Freckles
|
Darkened, flat spots that typically appear only on sun-exposed areas of the skin. Freckles are common in people with blond or red hair.
|
No treatment is needed for freckles.
|
|
Keloids
|
Smooth, firm, raised, fibrous growths on the skin that form in wound sites. Keloids are more common in people with dark skin.
|
Keloids respond poorly to most treatment approaches. Injections of corticosteroid drugs may help to flatten the keloids. Other treatment approaches may include surgery, laser treatment, external radiation, or silicone patches to further flatten the keloids.
|
|
Lipomas
|
Round or oval lumps, easily movable lumps under the skin caused by fatty deposits. They tend to appear on the forearms, torso, and back of the neck.
|
Lipomas are generally harmless. But if the lipoma changes shape, a biopsy may be advised. Treatment may include surgical removal if the lipoma bothers the child.
|
|
Moles (nevi)
|
Small skin marks caused by pigment-producing cells in the skin. Moles can be flat or raised, smooth or rough, and some contain hair. Most moles are dark brown or black. Some are skin-colored or yellowish. Moles can change over time and often respond to hormonal changes.
|
Most moles are benign and no treatment is needed. Some benign moles may develop into skin cancer (melanoma). See below for signs.
|
|
Atypical moles (dysplastic nevi)
|
Atypical moles are larger than normal moles) and are not always round. Atypical moles can be tan to dark brown, on a pink background. These types of moles may happen anywhere on the body.
|
Treatment may include removal of any atypical mole that changes in color, shape, or diameter. People with atypical moles should avoid sun exposure, since sunlight may accelerate changes in atypical moles. People with atypical moles should talk with a healthcare provider about any changes that may indicate skin cancer.
|
|
Pyogenic granulomas
|
Red, brown, or bluish-black, raised marks caused by excessive growth of capillaries (small blood vessels). Pyogenic granulomas usually form after an injury to the skin.
They tend to bleed easily.
|
Some pyogenic granulomas disappear without treatment. Sometimes, a biopsy is needed to rule out cancer. Treatment may include surgical removal.
|
|
Epidermoid cysts
|
Also called epidermal inclusion cysts, these are common benign lumps. They usually don't cause discomfort unless they become inflamed or infected. They range from a half inch to greater in size and are common on the back, head, and neck. They are firm and contain a white substance.
|
Treatment to remove the cyst is not needed unless the cyst becomes inflamed, or if its location is a problem. Epidermoid cysts sometimes go away without treatment but may return.
