Dermatofibromas

Dermatofibromas are small reddish-brown bumps on your skin. They're usually less than half an inch (about 1 centimeter) wide.

• Dermatofibromas are harmless

• They're common in adults, especially women

Dermatofibromas are caused by a certain gene you inherit from your parents. Some people get many of them.

• Small, firm bumps, often on your thighs or legs

• Usually no symptoms, but in rare cases they itch

Usually, doctors don’t treat them.

If a dermatofibroma grows bigger or bothers you, your doctor can cut it out with a scalpel (surgical knife).
