ALA-PDT combined with 2940 nm ablative fractional Er:YAG laser for Darier's disease.

ABSTRACT

Darier's disease is a rare, genetically determined dyskeratotic skin disorder. Although many conventional treatments have been reported, management of Darier's disease remains challenging. Most patients are at high risk of recurrence during long-term follow-up. Here, we present two patients who were successfully treated with ALA photodynamic therapy (PDT) and ablative 2940 nm ErYAG fractional laser. Both patients exhibited significant improvements in the affected areas with moderate pain, transient erythema and edema. Remission durations of up to 2 years were observed in both patients after combination treatment. Our findings suggest that the combination of ALA-PDT and 2940 nm fractional ErYAG laser may be an effective, safe and well-tolerated treatment option for Darier's disease.
