Scars are formed by the collagen produced by fibroblasts in the area of the injury. Initially scars may have a raised or bumpy appearance, but over time tend to diminish in size and flatten. Sometimes, however, fibroblasts do not cease to produce collagen at the proper time, and the resultant scar swells with the fibrous protein to unusual proportions. If this growth remains restricted to the original location of the wound then it is referred to as a hypertrophic scar, but if it extends past the boundaries of the injured area, then the overgrown scar is called a keloid.
