Treatment of a Chronic Cutaneous Surgical Wound With Platelet-Rich Fibrin
Platelet-rich fibrin (PRF) is a fibrin lattice that contains platelets, growth factors, and cytokines, which gives it unique wound healing properties. The PRF process was originally developed for oral and maxillofacial surgery.1 Excisions of skin cancers are common procedures in dermatology. One repair option is to allow a defect to heal by secondary intention. Occasionally, these wounds do not heal and develop into a chronic ulcer. To the authors' knowledge, this is the first report of applying PRF to a chronic wound after cutaneous surgery.
