Abstract: 【Abstract】 Localized scleroderma （LS） is a rare skin disorder characterized by fibrosis in the dermis and subcutaneous tissues. In severe cases, it can affect patients′ appearance, physical function, and quality of life. Currently, there is a lack of Chinese guidelines or consensus on the diagnosis and treatment of LS, leading to variability in clinical practice. To enhance dermatologists′ understanding of LS and standardize its diagnosis and management, the Chinese Society of Dermatology and the China Dermatologist Association organized a panel of leading experts in the field of dermatology to develop a consensus through systematic literature review and integration of recent Chinese and international research advances. The consensus comprehensively summarized the clinical subtypes, diagnostic criteria, differential diagnoses, and assessment methods of LS, as well as treatment strategies for LS, aiming to provide evidence-based guidance for standardizing the clinical management of LS in China.
