||Both hypertrophic scars and keloids initially present as red, raised, and firm tissue at the site of an incision orpcar injury. Hypertrophic scars remain within the confines of the wound and flatten spontaneously over one or more years. By contrast, keloids not only persist but frequently extend beyond the site of the original injury. Keloids occur more commonly in blacks than in whites and develop more frequently in the second and third decades of life.
This patient's earring was pulled through her ear by a young child 2 years previously. A hypertrophic scar has developed in the site of the laceration.
