Advances in Treatment Resistant Port-Wine Birthmarks: Emerging Therapies and Future Directions

Kristen Marie Kelly, MD, FAAD, highlighted promising advancements in the treatment of vascular malformations, particularly port-wine birthmarks at the American Academy of Dermatology (AAD) Annual Meeting.¹ Although lasers have significantly improved patient outcomes, she said, some lesions remain resistant, and recurrence continues to be a challenge. However, Kelly said new research offers hope for more effective therapies.

According to Kelly, chair and professor of dermatology at the School of Medicine, University of California, Irvine, energy-based devices remain a cornerstone of treatment, but there are emerging strategies that involve combining them with targeted medications. In her talk, “What's Next: Future Directions for the Treatment of Port Wine Birthmarks,” she explained a deeper understanding of the genetic mutations underlying vascular malformations is paving the way for innovative approaches. “Our treatments have improved, but for resistant lesions, there is hope for the future,” she said.

Recent studies have explored the potential of adjuvant therapies, including rapamycin and imiquimod, but these have produced only modest benefits, Kelly told Dermatology Times. However, ongoing aim to identify medications that more precisely target the affected pathways. Kelly said, “New drugs are being screened, and my hope is that when we find one that really targets that pathway, the combination will be very powerful.”

Kelly emphasized the importance of continued research and professional education. For those who want to be sure to stay up to date, she suggested attending conferences such as AAD Annual Meeting. The American Society for Lasers in Medicine and Surgery (ASLMS) is also a useful resource, she said, as they provide key platforms for dermatologists to stay updated on the latest advancements. “There’s a lot of research going on in terms of new potential treatments, and people should continue to watch for more exciting options,” she told Dermatology Times.

With the integration of genetic insights, novel therapeutics, and advanced laser technologies, the future of port-wine birthmark treatment is evolving and is promising, Kelly indicated. For dermatologists, she added, staying informed about these developments will be crucial in optimizing patient care and improving long-term outcomes.
