ABERRATIONS IN WOUND HEALING
· Delayed wound healing may be seen in wounds complicated by foreign bod-ies, infection, ischemia, diabetes, malnutrition, scurvy, etc.
· Hypertrophic scar results in a prominent scar that is localized to the wound,due to excess production of granulation tissue and collagen. It is common in burn patients.
· Keloid formation is a genetic predisposition that is common in African Amer-icans. It tends to affect the earlobes, face, neck, sternum, and forearms, and it may produce large tumor-like scars extending beyond the injury site. There is excess production of collagen that is predominantly type III.
