It is a result of an overgrowth of granulation tissue (collagen type 3) at the site of a healed skin injury which is then slowly replaced by collagen type 1. Keloids are firm, rubbery lesions or shiny, fibrous nodules, and can vary from pink to the color of the person's skin or red to dark brown in color. A keloid scar is benign and

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
