Complications following pulsed dye laser treatment of superficial hemangiomas.
OBJECTIVE
Pulsed dye laser (PDL) has been reported to be safe and effective in the management of superficial hemangiomas of infancy. We report 12 patients with hemangiomas with complications following PDL.


METHODS
Records of patients with hemangiomas and a known adverse outcome following PDL were reviewed.


RESULTS
All were treated early (age range: 5 days to 4 months), and all hemangiomas were facial with a superficial component. Eleven were treated with a 585 nm wavelength, fluence range of 4.7-7 J/cm(2), without dynamic cooling. One patient received 7-12 J/cm(2) utilizing a 595 nm wavelength with dynamic cooling. In eight cases, treatment led to severe ulceration with subsequent pain, scarring, and in one instance, life-threatening hemorrhage. In four, permanent atrophic scarring was noted without ulceration.


CONCLUSIONS
PDL treatment of superficial hemangiomas may rarely lead to significant complications including atrophic scarring and severe ulceration.
