What type of scarring is characterized by an overproduction of collagen after skin trauma or injury?

Keloid
Atrophic
Hypertrophic
Contracture

The correct answer is: Keloid

The type of scarring characterized by an overproduction of collagen following skin trauma or injury is a keloid scar. Keloids occur when the body's healing process leads to an excessive accumulation of collagen, resulting in a thick, raised area on the skin that often extends beyond the original wound site. These scars can be variable in size and may continue to grow over time. Hypertrophic scars are also a result of collagen overproduction, but they remain confined to the original injury site and often improve in appearance over time. In contrast, atrophic scars are depressed scars that occur when there is a loss of tissue, leading to a sunken appearance, while contracture scars involve the tightening of the skin, which can limit movement, usually as a result of severe burns.
