Dermatofibromas

Dermatofibromas are usually red or brown firm nodules in the skin, commonly found on women's legs. They can also be on the arms, back or torso in men or women.  They occur from the growth of excessive scar tissue after a minor injury to the skin, such as an insect bite or an ingrown hair.  These growths are not cancerous, but they do not go away on their own.  People sometimes desire removal for reasons of unsightliness or difficulty shaving.  Dermatofibromas cannot just be shaved off of the surface, they do need to be excised with and stitches in order to be completely removed so they don't grow back , since much of the growth is below the skin. Excision does cause a scar as well, although usually the scar may be flatter and less noticeable than the dermatofibroma.
