There are few epidemiologic investigations on keloids in the world. It is well known that there is a racial difference in the incidence, and sometimes keloids are inherited. Moreover, it has been suggested that there is some kind of relationship between allergic / autoimmune diseases and keloids. What is more, there are hypotheses such as keloid patients have a low risk of developing cancer, and schizophrenia patients have a low risk of developing keloids. These interesting hypotheses may be verified in large / world wide epidemiologic investigations on keloids.
