PATHOLOGY

Detailed explanation-1: -A keloid scar is a thick raised scar. It can occur wherever you have a skin injury but usually forms on earlobes, shoulders, cheeks or the chest. If you’re prone to developing keloids, you might get them in more than one place.

Detailed explanation-2: -Keloids are dermal fibrotic lesions that are a variation of the normal wound healing process. They usually occur during the healing of a deep skin wound. Hypertrophic scars and keloids are both included in the spectrum of fibroproliferative disorders.

Detailed explanation-3: -Keloids are nodules that develop on the surface of the skin following an injury or trauma to that area. When skin is injured, scar tissue usually forms over the wound to help protect and heal it, but an excess or overgrowth of scar tissue can trigger the growth of a keloid.

Detailed explanation-4: -Hypertrophic scars are contained within the site of injury and may regress over time, while keloids spread beyond the borders of the initial injury and do not regress.
