Keloids are firm, fibrous tissue nodules typically found in areas of previous skin trauma, such as scars or burns. They can be single or scattered throughout an area of the skin. Keloids may become itchy, painful, and grow to very large sizes in the weeks following an inciting trigger. Keloids can be very disfiguring, restrict normal motion and cause significant discomfort. Keloids are most common in African-Americans and those of Mediterranean descent, but may appear in all ethnicities.
