Keloid Scars are scars which abnormally grow further than the border of the unique location of an injury of the skin. They are normally raised and often poorly defined skin growth in the location of the injured skin. Almost anyone can have a Keloid Scar form but there are some ethnic groups which are at a greater risk for having them occur. African-Americans and Hispanics are approximately 16% more apt for developing these scars. They are also 15 times more often seen in ethnic groups which are highly pigmented rather than Caucasians.
A Keloid is a heaped-up, touch scar which rises usually abruptly above the rest of the skin. They are dome-shaped and shiny and range in color from red to pink. Some Keloids can become very large and unattractive. Also besides the cosmetic problems, these scars can be very itchy, painful to the touch as well as very tender. They are shaped irregularly and are inclined to progressively enlarge. Unlike a normal scar, keloids do not go away over time.
Keloid Scars are not understood fully as to why or how they happen. Trauma of the skin seems to be the most common factor but they can form and have no apparent cause. Muscle tension with the skin seems to contribute to their formation and this is seen by the more common sites where they form such as the upper arm as well as the back. Now if this were the total story you might expect that they would appear on other sites such as palms of the hand or the bottom of the feet as they are just as exposed, but that is not the case. Other factors can be repeated trauma to the exact area, infection at wound site, foreign body in the wound, are skin tension in the wound.
