Abstract
This report describes a case of local pyoderma gangrenosum that was treated with short-term immunosuppressive therapy and the topical application of platelet-rich fibrin (PRF). Medical treatment included oral corticosteroid therapy and topical treatment with PRF in solid and liquid form. This therapy initially led to the reduction of the ulcer's size and an improvement in symptoms, until the ulcer was completely healed after a few weeks. A relapse was treated with only the application of PRF to the affected tissue with excellent recovery. The efficacy of PRF as a guide for wound healing is a result of the continuous release of growth factors involved in tissue repair mechanisms. PRF has proved to be suitable for the management of facial pyoderma gangrenosum while allowing a reduction in systemic corticosteroid therapy. The ease of preparation, low cost, and outpatient use make PRF an optimal scaffold for tissue healing processes.
