Keloids are a type of abnormal scar that forms when the body produces excessive collagen during the healing process. They are characterized by their elevated and often thickened appearance and can extend beyond the original boundaries of the wound, resulting in a scar that is larger than the initial injury. This overproduction of tissue occurs as the body attempts to heal itself, but it leads to the formation of a raised scar that does not regress over time like a normal scar would. Keloids can also be itchy or painful and might cause cosmetic concerns for individuals, depending on their size and location.

In contrast, other scar types, such as flat scars or scars that are smaller than the original wound, do not have the same characteristics as keloids. Keloids are unique in their tendency to grow past the original wound site, which makes the understanding and management of such scars important in post-operative care and rehabilitation.
