What is the term used to describe a significant scarring condition due to tissue growth?

Keloids are a type of raised scar that occurs when there is an overproduction of collagen during the healing process of a wound. They can be firm and rubbery, often extending beyond the original injury site due to excessive tissue growth. This hyperplastic scar tissue can be persistent and may not respond well to traditional treatments. Keloids are characterized by their thick, irregular appearance, distinguishing them from other types of scars or skin conditions.

In contrast, a crust refers to a collection of dried serum, blood, or pus on the surface of a wound, while a scale involves flaky or dry patches of skin. A fissure describes a crack or gap in the skin or mucous membrane. Each of these terms depicts different skin conditions that do not share the same characteristics as keloids, which are specifically related to abnormal scarring and tissue growth.
