Background

What is a keloid?

A keloid is a benign fibroproliferative growth −resulting from a connective tissue response to a variety of proposed factors such as surgery, burns, trauma, inflammation, foreign body reactions, endocrine −dysfunction, and occasional spontaneous occurrence.

Is there a racial predilection for keloid formation?

Yes. People of African descent are more likely to be predisposed to keloid formation than other ethnic groups. Any skin insult (piercings, lacerations, infected skin lesions, surgery) can cause keloid formation in predisposed individuals. Less commonly, lesions can occur de novo.
