What are benign skin growths?
Benign skin growths are non-cancerous bumps, spots, and lumps on the skin. While many benign skin growths can be ignored, some need to be monitored and others treated for medical or cosmetic reasons.
There are a variety of different types of benign skin growths, some of which do not require medical treatment, like non-cancerous bumps, spots, and lumps.
Certain types of moles are at higher risk for changing into cancerous growths, including malignant melanoma, a form of skin cancer.
Parents should monitor their children's moles over time and report any changes to their child's physician.
What are the different types of skin growths?
- Small, firm red or brown bumps caused by an accumulation of soft tissue cells under the skin, called fibroblasts. They often occur on the legs and may itch.
- Dermatofibromas can be surgically removed if they become painful or itchy.
- A benign tumor made up of hairs, sweat glands, and sebaceous glands, which are located in the middle layer of the skin. Some internal dermoid tumors may even contain cartilage, bone fragments, and even 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 options 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 removal by surgery if the lipoma bothers your 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).
