Keloid and hypertrophic scars are elevated lesions that can form following trauma to the body surface, and they are a condition with comparatively many opportunities for routine treatment.
The earliest record of keloids dates back to the age of the pyramids when the Smith Papyrus was written at around 1600 B.C. That is to say, keloid and hypertrophic scarring are troublesome conditions which have continually burdened human beings from ancient times up to today. Many aspects of the mechanism of keloid and hypertrophic scar formation, their pathological condition and their resolution remain unknown, and constitutional or genetic factors are strongly suggested to be involved. Treatments that have been tried include surgical removal followed by electron beam irradiation, tranilast medication, application of silicone materials and compression therapy.
We describe the current status of keloid and hypertrophic scar classification and treatment and their future prospects, including a new classification which is now being conveyed through the Japanese Scar Workshop.
