title: Photodynamic therapy in a teenage girl with xeroderma pigmentosum type C.
abstract: Despite aggressive sun protection, most individuals with xeroderma pigmentosum (XP) develop cutaneous neoplasia, including actinic keratoses. We describe the case of a 16-year-old girl with XP type C treated safely with photodynamic therapy (PDT). Although there is little if any evidence in the literature supporting the use of aminolevulinic acid PDT in individuals with XP, they may be the ideal candidates for PDT treatment because the profound post-treatment photosensitivity and strict post-therapy sun avoidance necessitated by PDT treatment is already part of the everyday lifestyle of people with XP.
