When the scar from a cut or wound extends and spreads beyond the size of the original wound, it is known as a keloid. Keloids may vary in size, shape, and location and are found more often in people with darker skin pigmentation.

Common on the ear lobes, chest, back, or arms, keloids usually occur after an injury or infection. Occasionally, they occur spontaneously, especially on the mid-chest. Keloids frequently develop after surgery or after ear piercing.

Depending on the location, treatment may consist of cortisone injections, pressure dressings, silicone gels, surgery, laser treatment, cryosurgery, liquid nitrogen, radiation therapy, or combination therapy. Unfortunately, keloids are difficult to treat and tend to return, sometimes larger than before. Patients must be motivated and agreeable to following up with the dermatologist after a keloid is removed. Newer regimens are being developed and certain products that can help reduce keloid scarring are available at Miramar Dermatology/Skin and Cancer Associates.
