Keloids and hypertrophic scars represent the benign proliferation of collagen in derm, resulting from a cutaneous traumatism, dermatosis, or appearing spontaneously. Treatment is frequently marked by therapeutic failures. The first rule in the appearance of keloids and hypertrophic scars is to prevent them. The used therapeutic methods are the following: surgical methods (excision, laser, cryotherapy), biophysical methods (radiotherapy, compressive therapy, therapeutic massage, ultrasounds) and drug therapies. None of the therapeutic methods is efficient for all patients. For better results it is recommended to make therapeutic associations. There is no unanimously recognized therapeutic protocol.
