PATHOLOGY

Detailed explanation-1: -A hypertrophic scar is a thick raised scar. It’s an abnormal response to wound healing in which extra connective tissue forms within the original wound area.

Detailed explanation-2: -A keloid scar is an overgrowth of tissue that happens when too much collagen is produced at the site of a wound. The scar keeps growing, even after the wound has healed.

Detailed explanation-3: -Keloids result from abnormal wound healing in response to skin trauma or inflammation. Keloid development rests on genetic and environmental factors. Higher incidences are seen in darker skinned individuals of African, Asian, and Hispanic descent.

Detailed explanation-4: -After your skin is injured, your cells try to repair it by forming a scar. In some people, the scar tissue keeps forming long after the wound heals. This extra scar tissue causes the raised area on your skin that is called a keloid. Doctors still aren’t sure why some people’s skin scars this way.
