Linear scleroderma en coup de sabre is a rare chronic autoimmune disease. This form of localized scleroderma manifests through an inflammatory phenomenon of collagen overproduction and extracellular matrix destruction, affecting the skin and subcutaneous tissues of the face. This active pathological process is challenging to control and often goes unnoticed at its early stage. The sequelae manifest as an alopecic frontal scar lesion, causing the patient significant aesthetic and psychological damage. In this study, we report two clinical cases in which aesthetic sequelae were treated by autologous fat transplantation. We found encouraging results, with a global aesthetic improvement of 86.2% measured by a jury of medical specialists and outcome stability through a nine-year follow-up for one patient. Autologous fat transfer is excellent for treating stabilized en coup de sabre morphea, not only for its filling abilities but also for its regeneration activating and inflammation regulating abilities, which could open new prospects for curative treatment of this pathology.
