Small, firm, red or brown bumps caused by an accumulation of fibroblasts (soft tissue cells under the skin). They often occur on the legs and may itch.
Dermatofibromas can be surgically removed if they become painful or itchy.
A benign tumor which is made up of hairs, sweat glands, and sebaceous glands. Some internal dermoid tumors may even contain cartilage, bone fragments, and teeth.
Dermoid cysts may be surgically removed for cosmetic reasons.
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 necessary for freckles.
Smooth, firm, raised, fibrous growths on the skin that form in wound sites. Keloids are more common in African-Americans.
Keloids respond poorly to most treatment approaches. Injections of corticosteroid drugs may help to flatten the keloids. Other treatment approaches may include surgery or silicone patches to further flatten the keloids.
Round or oval lumps under the skin caused by fatty deposits. Lipomas are more common in women and tend to appear on the forearms, torso, and back of the neck.
Lipomas are generally harmless, but if the lipoma changes shape, your physician may perform a biopsy. Treatment may include surgical removal if the lipoma bothers the child.
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, but 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 necessary. Some benign moles may develop into skin cancer (melanoma). See below for signs.
Atypical moles (dysplastic nevi)
Larger than normal moles (more than a half inch across), atypical moles are not always round. Atypical moles can be tan to dark brown, on a pink background. These types of moles may occur anywhere on the body.
Treatment may include removal of any atypical mole that changes in color, shape, and/or diameter. In addition, people with atypical moles should avoid sun exposure, since sunlight may accelerate changes in atypical moles. Persons with atypical moles should consult a physician for any changes that may indicate skin cancer.
Red, brown, or bluish-black, raised marks caused by excessive growth of capillaries (small blood vessels) and swelling. Pyogenic granulomas usually form after an injury to the skin.
Some pyogenic granulomas disappear without treatment. Sometimes, a biopsy is necessary to rule out cancer. Treatment may include surgical removal.
