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
