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.
