Which characteristic is more typical of a keloid compared to a hypertrophic scar?

A keloid is characterized by its tendency to expand beyond the margins of the original injury site. This feature distinguishes it from a hypertrophic scar, which typically remains confined to the boundaries of the wound and often exhibits a raised but not overly expanded appearance. Keloids can grow significantly larger than the initial area of trauma, which can lead to noticeable cosmetic concerns and discomfort for the individual.

The growth pattern of keloids is linked to an overproduction of collagen during the healing process, and they may continue to grow over time, making them more prominent. In contrast, hypertrophic scars usually respond well to treatment and may flatten over time, remaining within the original injury’s dimensions.

Understanding this distinction is crucial for proper diagnosis and treatment options, as interventions may differ for keloids compared to hypertrophic scars.
