In this type of scar, the scar tissue extends beyond the boundary of the injury into normal tissue.

Granuloma.
Hypertrophic scar.
Inhibitory scar.
Keloid scar.

The correct answer is: Keloid scar.

A keloid scar is characterized by an overproduction of collagen during the healing process, which leads to the growth of scar tissue that extends beyond the original boundaries of the wound into surrounding healthy skin. This overgrowth can result in a raised, thickened appearance. Keloids are often larger than the original injury and can be itchy or painful. Their formation is a result of a hyperactive healing response, and they occur more frequently in certain individuals, especially those with darker skin tones. Understanding the nature of keloids is essential for treatment, as they may require different management approaches compared to other types of scars, such as hypertrophic scars, which remain within the injury's boundaries and often improve over time.
