The incidence and clinical manifestations of scars and keloids are different in different races, and Asians are more likely to suffer from this disease than Caucasians. China and Japan are the representative countries for medical development in Asia. There is no comprehensive study on the similarities and differences between the academic circles in the two countries in the diagnosis and treatment of scars and keloids. By comparing and analyzing the latest expert consensus in the field of scars and keloids between the two countries, we found that the organization form of expert team and main contents of the consensus from the two countries are basically similar. However, there are obvious differences in the composition of experts, logical thinking and organizational form of consensus contents, and details of the specific schemes for scar assessment, diagnosis, and treatment. The differences in the diagnosis and treatment of scars and keloids in China and Japan may indicate the direction of future cooperative research. It is necessary for the academic circles of China and Japan to strengthen academic exchanges and work hard to cooperate in high-quality research in the field of scars and keloids.
