What Is It?
Dermatofibromas are small, noncancerous (benign) skin growths that can develop anywhere on the body but most often appear on the lower legs, upper arms or upper back.

They are firm and often feel like a stone under the skin. When pinched from the sides, the top of the growth may dimple inward.
