Hypertrophic scar

    Clinical Features:

    • Raised, exuberant scars that remain localized to the wound area, in contrast to keloids, which grow beyond the wound area
    • The clinical and histologic distinction between hypertrophic scars and keloids is not always crisp.

    Histologic Features:

    • Dense collagen bundles oriented parallel to the epidermal surface
    • Marked increase in fibroblasts in the area of the hypertrophic collagen 
    • The scar shows minimal to no elevation above the skin surface (in contrast to keloids).
