Photodynamic therapy (PDT) with light emitting diode (LED) illumination is a frequently used treatment modality for actinic keratosis (AK) with excellent cosmetic outcome. A major disadvantage, however, is the high pain score. Pulsed dye laser (PDL) illumination has been suggested, but the long-term efficacy of this treatment is unknown. In this split-face(More)
BACKGROUND AND OBJECTIVES Childhood hemangioma is the most common soft tissue tumor of infancy, occurring in 10% of children younger than 1 year old. Ten percent of these infantile hemangiomas involute yearly without intervention. Treatment with the pulsed dye laser (PDL) is the criterion standard for treating vascular lesions. It is well established as the(More)
BACKGROUND There is limited literature on efficacy using a 2-fold illumination scheme in aminolevulinic acid (ALA) photodynamic therapy for superficial basal cell carcinoma (sBCC). OBJECTIVES We sought to determine the efficacy of ALA photodynamic therapy for sBCC using a 2-fold illumination scheme after a single ALA application. Treatment failure within(More)
BACKGROUND Basal cell carcinoma (BCC) is the most common type of skin cancer with growing incidence rates. Photodynamic therapy (PDT) is a frequently used treatment, especially for superficial BCC (sBCC). Two topical photosensitizing agents are currently used to treat sBCC: 5-aminolevulinic acid (ALA) and its methyl-ester (MAL). Previous research showed a(More)
