Keloid

    Clinical Features:

    • Scars that grow beyond the area of the wound that provoked them (in contrast to hypertrophic scars, which remain localized to the wound area).
    • The clinical and histologic distinction between keloids and hypertrophic scars is not always crisp.
    • Keloids can sometimes become quite disfiguring when of large size. 
    • Their etiology is unknown. 
    • They are significantly more common in blacks.

    Histologic Features:

    • Broad, haphazardly arranged, brightly eosinophilic collagen bundles
    • Increased fibroblasts interspersed among the collagen bundles
    • Usually elevated above the skin surface, often with an atrophic overlying epidermis
