Laser treatment has also been used with varying degrees of success. Keloids form within scar tissue. Collagen, used in wound repair, tends to overgrow in this area, sometimes producing a lump many times larger than that of the original scar. They can also range in color from pink to red. Although they usually occur at the site of an injury, keloids can also arise
Circumcision scar in a fine, even scar. Circumcisions after the newborn period that are performed without sutures (techniques that use cyanoacrylate tissue adhesive instead of sutures and techniques like Plastibell that heal by secondary intention) often result in an even, circumferential scar. There is some controversy as to what happens to the severed nerves of the foreskin at the scar. Xin "et al". (1997) suggest that nerves regenerate, forming new receptors. However, pathologists Cold & Taylor (1999) report: "Histology of the male circumcision scar shows amputation neuromas, Schwann cell proliferation and the bulbous collection of variably sized neurites. Amputation neuromas do not
