Abstract: There are many kinds of rare skin diseases, but the research into the diagnosis and treatment of rare skin diseases is relatively scarce. In recent years, the rare skin diseases team has made a series of accomplishments, including establishing the professional committee of Rare Skin Disease Committee of China Alliance for Rare Diseases, establishing China's first Medical Care Alliance for Rare Skin Diseases, launching two national collaborative projects, promoting the project of improving the diagnosis and treatment of rare diseases supported by the Central Special Lottery public welfare Fund, exploring the multidisciplinary diagnosis and treatment model of skin rare diseases, holding academic conferences, and compiling professional books on rare skin diseases. In the future, we will further improve the remote consultation model of rare skin diseases, develop artificial intelligence assisted diagnosis system of rare skin diseases, carry out high-quality clinical research, and improve the overall diagnosis and treatment level of rare skin diseases in China, for the sake of benefiting more patients.
