Angiolymphoid hyperplasia successfully treated with an ultralong pulsed dye laser.

Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a benign vascular proliferation characterized by dermal or subcutaneous nodules or both, primarily in the head and neck. We report the successful treatment of ALHE without scarring using a 595 nm ultralong pulsed dye laser, which applies a unique combination of longer wavelengths, a longer pulse duration, and a higher fluence.

Objective: To report the use of the 595 nm pulsed dye laser in the treatment of ALHE and to detail the particular aspects of this laser that make it uniquely qualified to treat this entity.

Methods: Case report and review of the literature.

Conclusions: This laser may be used as an effective treatment for ALHE and has advantages over alternative treatments and older lasers. Specifically, the longer wavelength (595 nm) penetrates more deeply into dermal tissue, which produces more uniform coagulation across the entire vessel.
