keloid
Pronunciation: KEE-loyd
Raised, thickened scar that extends beyond the original wound boundaries and tends to recur.
Full Definition
A keloid is an abnormal type of scar characterized by excessive collagen formation that extends beyond the original injury site. Unlike hypertrophic scars, keloids grow beyond the wound margins and have a high tendency to recur after treatment. They are more common in certain ethnic populations and specific body areas such as the chest, shoulders, and earlobes. In plastic surgery, keloid formation is a significant concern that affects surgical planning and patient selection.
Usage
Usage note: Distinguish from hypertrophic scars, which remain within wound boundaries and may improve over time.
