Hypertrophic scars are red and tense and persist for several months. They are larger in size and more elevated than the expected one for the particular trauma. A part of the scar may look normal, while another may seem hypertrophic. Unlike keloids, hypertrophic scars are limited to the wound area and show a tendency to recede. Pruritus and sensitivity are often observed.
The keloids are even larger, more elevated and often sensitive. They extend beyond the wound site and often disrupt the anatomy of this area. They do not show a tendency to retreat, and usually their size is increasing over time.
Recent lesions respond better than older, less active scars. The treatment of these scars includes topical corticosteroids, laser therapy and surgical correction.
