Background: Multiple eccrine hidrocystomas are benign cystic lesions that pose a significant treatment challenge due to their facial location and tendency to scar after traditional surgical and other destructive modalities.
Methods: A 585nm pulsed dye laser was used at fluences ranging 7.0 J/cm2 to 7.5 J/cm2 at 6- to 8-week intervals to treat multiple lesions on the face of a 54-year-old man.
Results: Near complete resolution of all papules was seen after four laser sessions. There was no evidence of lesional recurrence 18 months after the final treatment.
Conclusion: The 585nm pulsed dye laser can effectively treat eccrine hidrocystomas. The mechanism of action whereby this vascular-specific laser produced improvement is unclear.
