Which of the following is a feature of keloid scars?

Keloid scars are characterized by their raised nature and growth beyond the parameters of the original injury. When the skin undergoes injury, the healing process may sometimes produce an excess of collagen, leading to the formation of a keloid. Unlike normal scars that typically remain within the borders of the wound, keloids extend outward, creating a prominent, raised scar that can be larger than the original site of injury.

Keloids can occur at any site on the body and are not limited to the face, which gives their occurrence a more widespread impact rather than being localized. This unique feature of exceeding the wound borders distinguishes keloids from other types of scars, such as hypertrophic scars that may be raised but do not go beyond the original injury.

Understanding the growth pattern of keloid scars is essential for health professionals in terms of prevention and treatment strategies, as well as informing patients about the likelihood of their occurrence following surgical procedures or injuries.
