RESUMEN

Objective: To evaluate the efficacy and safety of platelet-rich plasma to restore skin changes in morphea by ultrasound and Localized Scleroderma Cutaneous Assessment Tool. Methods: Nine morphea patients (21 lesions) were diagnosed clinically and by histopathology. Intradermal platelet-rich plasma was injected into morphea lesion once weekly for 12 sessions. The disease severity and damage were evaluated at baseline, after the last session (3 months later), and at 6 months follow-up using the LoSCAT and a high-resolution ultrasound. The healthy corresponding side was considered as a control. Results: The Localized Scleroderma Cutaneous Assessment Tool score showed a significant improvement starting from 13 ± 7.28 up to 7.33 ± 6.82 after the therapeutic endpoint, reaching to 6.44 ± 7.09 after 6 months of follow-up with p value = 0.008 and 0.014, respectively. There was a significant positive correlation between the duration of the lesion and the improvement assessed by the ultrasound, with p value = 0.01. Regarding adverse effects, all patients reported having pain during platelet-rich plasma injection; transient edema of the face was reported by four patients (45%), and only two patients showed transient erythema. Conclusion: Autologous platelet-rich plasma is a safe technique with great aesthetic outcomes for filling up the contour defects and correcting both hyper and hypopigmentation, in addition to softening the indurated lesions.
