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.
