Successful treatment of facial hypertrophic scar with HMME-PDT: A case report.

Treating hypertrophic scars is a challenge for clinicians. Herein, we report a case of one female with both a facial port wine stain and a hypertrophic scar treated with Hematoporphyrin monomethyl ether photodynamic therapy. Surprisingly, with the treatment of the facial port wine stain, the other skin lesion, the hypertrophic scar, also alleviated. HMME-PDT has been approved for application in PWS; however, this case showed effective easing of the hypertrophic scar lesion, which indicates that it might be a promising therapeutic method for hypertrophic scars.
