Abstract (original English)

Morphea is a chronic autoimmune condition characterized by sclerosis and scar-like changes in the skin and underlying tissues. En coup de sabre represents a rare and severe linear variant of morphea, primarily affecting the frontoparietal scalp and forehead, with a higher prevalence among children and women. The disease often leads to significant cosmetic and functional impairments, posing therapeutic challenges due to its unpredictable course and varying responses to conventional treatments. Current management strategies include topical steroids, calcineurin inhibitors, systemic therapies, such as methotrexate, and ultraviolet (UV) therapy. Additionally, interventions like fat grafting and hyaluronic acid injections have demonstrated some efficacy in restoring tissue volume and improving skin texture. This case report explores an innovative approach using autologous fibroblast cell injection combined with platelet-rich plasma (PRP) as a novel therapeutic option for a 40-year-old woman diagnosed with inactive-phase en coup de sabre. After harvesting fibroblast cells from a superficial skin biopsy and isolating PRP through centrifugation, the combined solution was administered via three monthly subcutaneous injections. No adverse effects were observed throughout the treatment period. At a 3-month follow-up, significant improvements were noted in skin elasticity, hydration, and o
