Hypertrophic scar

Hypertrophic scars are formed shortly after wound healing and are caused by excessive production of connective tissue fibres. The scar tends to bulge and protrudes above the level of the surrounding skin, although it remains limited to the area of the original wound. The scar does not extend beyond the wound edges. Hypertrophic scars are particularly common if the wound has not been immobilized or protected or if it is infected.
