In a strict sense, hypertrophic scars and keloids are similar in their pathogenesis. For hypertrophic scars, the typical presentation is localized overgrowth at the scar site, which means that there is an overgrowth during the wound healing process, resulting in a relatively large and numerous scar. Keloids represent a more severe condition where there is a localized raised scar on the wound, which can be significantly large, sometimes resembling a bug on the surface of the scar. They are more likely to occur in areas like the neck, behind the ears, and under the earlobes. For the treatment of hypertrophic scars and keloids, if the patient has a predisposition to scarring, considerations include early intervention during wound suturing and healing, such as injection of medications or radiation therapy.
