Photodynamic Therapy of Actinic Keratosis of the Face and Scalp With and Without Prior Curettage

Photodynamic Therapy of Actinic Keratosis of the Face and Scalp With and Without Prior Curettage

Guidelines for photodynamic therapy (PDT) of actinic keratosis recommend pretreatment with curettage. The impact of curettage on the treatment effect is, however, not known. The present study aimed to evaluate whether daylight-PDT without curettage would reduce treatment effect compared to daylight-PDT with curettage.

Inclusion Criteria:

- Multiple actinic keratosis on the forehead or scalp

Exclusion Criteria:

• Known allergy to methyl aminolevulinate
• Porphyria
• Pregnancy
• Lactation
