Any time dark skin is cut or burned, there's an increased risk of keloids -- a scar that spreads beyond the boundary of the original injury and develops into a growth. Symptoms may include itching, pain, burning, and tenderness at the site. Keloids are thought to be linked to a defect in collagen production. Treatments include cortisone injections, radiation therapy, pressure dressings, and silicone gel applications. Keloids can also be removed via surgery or with a laser.
