Keloid Keloid Keloid, also known as keloid disorder and keloidal scar, is the formation of a type of scar which, depending on its maturity, is composed mainly of either type III (early) or type I (late) collagen. 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
Dense regular connective tissue Dense regular connective tissue Dense regular connective tissue provides connection between different tissues in the human body. The collagen fibers in dense regular connective tissue are bundled in a parallel fashion. Dense regular connective tissue (DRCT) is divided into white fibrous connective tissue and yellow fibrous connective tissue, both of which occur in two forms: cord arrangement and sheet arrangement. In cord arrangement bundles of collagen and matrix are distributed in regular alternate patterns. In sheet arrangement collagen bundles and matrix are distributed in irregular patterns, sometimes in the form of a network. It is similar to areolar tissue, but
