Keloids and hypertrophic scars are fibroproliferative disorders of the skin caused by abnormal wound healing, and are characterized by chronic inflammation. A recent study on single nucleotide polymorphisms has suggested that keloid generation involves a genetic predisposition. Moreover, recent studies revealed that mechanical forces are important in the generation of such pathological scars. Thus, keloids and hypertrophic scars can be considered as a multifactorial disorder with a genetic disposition that has a tendency to be affected by local factors, such as mechanical force. Both mechanical force reduction and anti-inflammatory treatments play important roles in the current pathological scar-treatment strategy.
