Keloids and Hypertrophic Scars.

Keloids and hypertrophic scars are abnormal responses to wound-healing. While hypertrophic scars remain limited to the areas of trauma, keloids most often develop over several years, growing out from the limits of the initial wound area. Both lesions may cause itching, burning, and pain, and they may lead to significant impairment of self-esteem, socialization, and quality of life. Although they might be observed in all races, they are far more common in Africans and African descendants than in Caucasians.We extensively reviewed their treatment, including compression with pressure garments, occlusion with siliconized and non-siliconized gel sheets, gels, corticosteroid and antineoplastic injections, and the use of lasers and intense pulsed light (IPL) therapy. We also reviewed new therapies, including botulinum toxin injection, and addressed outcomes of various studies. ( SKINmed . 2022;20:432-443).
