Hemoporfin-mediated photodynamic therapy for the treatment of port-wine stain birthmarks in pediatric patients

Port-wine stain is a type of common congenital superficial telangiectasia in the dermal layer mostly occurring on the forehead,face,and neck. the affected skin shows abnormal red or purple lesions,which darken and thicken. nodular changes may develop with advancing age. if untreated,port-wine stains scarcely regress,which can have serious lifelong psychological impact on patients and affect their quality of life. in this report,we focused on two cases of port-wine stain in pediatric patients; the youngest patient was only 1.5 years old. during and after treatment,hemoporfin-mediated photodynamic therapy features fewer adverse reactions,short light protection period,easy nursing,and good efficacy. © 2017 by anais brasileiros de dermatologia.
