Photodynamic therapy: Clinical applications in dermatology.

Area of Science:

• Dermatology
• Photomedicine

Background:

• Photodynamic therapy (PDT) is a non-invasive treatment using photosensitizers and light to generate reactive oxygen species for therapeutic effects.
• PDT is FDA-approved for actinic keratoses and used off-label for numerous dermatologic conditions, demonstrating a favorable safety profile.

Purpose of the Study:

• To provide a comprehensive overview of the dermatologic clinical applications of Photodynamic Therapy (PDT).
• To guide dermatologists in understanding and incorporating evidence-based PDT protocols for improved patient outcomes.

Main Methods:

• Review of existing literature and clinical evidence for Photodynamic Therapy (PDT) applications in dermatology.
• Clinical descriptions and treatment protocols for various dermatologic diseases managed with PDT.

Main Results:

• PDT is effective for actinic keratoses and has demonstrated utility in treating basal cell carcinoma, cutaneous squamous cell carcinoma in situ, acne, and more.
• The therapy is also used for port wine stains, cutaneous infections, photoaging, actinic cheilitis, mycosis fungoides, rosacea, alopecia areata, and Extramammary Paget disease.

Conclusions:

• Photodynamic therapy (PDT) is a versatile and safe treatment option for a wide range of dermatologic conditions.
• Understanding the expanding evidence-based applications of PDT is crucial for optimizing patient care and treatment protocols.
