Abstract

|
|
The hypertrophic scar and keloid continue to baffle both clinician and researcher as there are still many pieces of the keloid puzzle that do not fit into place. Hypertrophic scars and keloids are a variation of the normal wound healing process. Those are benign tumors of dense fibrous tissue nonencapsulated, and with ill-defined margins, which developed in the dermis as an excessive over accumulation of collagen during a healing process.
The cause of keloids and hypertrophic scars is unknown. Trauma to the dermis is always the inciting factor, but other local and general factors are probably significant. Because the cause of keloids is unknown and probably is not the same for all people, treatment cannot be planned on a sound biological basis.
Although many attempts have been made and various signs advanced to distinguish hypertro-phic scars from keloids, conclusive test have not been developed to separate these two clinical terms. Even on a clinical basis, in the view of many observers, keloids seem to differ from sev-ere hypertrophic scarring only in the amount of scar production. All attempts to find some hist-ochemical, morphological, or any other biological or behavioral differences between these two types of abnormal scars have been unconvincing.
Race and heredity seem more important in keloid susceptibility than any other general factors known. The types of therapy most advocated are radiotherpy, surgery, and steroids, either individually or in combination.
