Summary
Photodynamic therapy (PDT) effectively cleared warts on tattooed skin without damaging the tattoo. This non-invasive treatment offers a safe alternative for warts in cosmetically sensitive areas.
Area of Science:
- Dermatology
- Photomedicine
Background:
- Cutaneous warts, caused by human papillomavirus (HPV), are common benign skin lesions.
- Conventional treatments for warts (cryotherapy, laser, electrosurgery) risk scarring and pigmentary changes on tattooed skin.
- Photodynamic therapy (PDT) is a non-invasive option targeting HPV-infected cells with minimal collateral damage.
