Abstract

Background: Port wine stains (PWS) are congenital malformations of capillaries, where with progression, blood vessels become ectatic and result in disfiguring nodules.
Objective: To search the MEDLINE database and review literature on the treatment of PWS and present 2 cases of adults with PWS, complicated by hypertrophic and nodular lesions, treated successfully with CO 2 laser.
Results: Two patients with PWS, with nodular and hypertrophic areas, were treated with CO 2 laser. With the first patient, improve- ment of 90% or greater was noted in the 14 discrete nodules present within the PWS in a V2 distribution. At baseline, ectropion of the lower eyelid was noted which resolved completely after CO 2 laser. With the second patient, improvement was noted as 90% or greater in the 40 of 51 discrete nodules present within the PWS extending across the right V1-V2 distribution.
Conclusion: Carbon dioxide ablative laser resurfacing is safe and highly effective in the treatment of the nodular and hypertrophic components of PWS. Future treatment of PWS will likely involve a hybrid approach of utilizing nonablative lasers of varying wave- lengths and pulse durations and treatment with novel laser devices, with the goal of early treatment to prevent progression of PWS to disfiguring lesions.
