A child presensted with erythematous non blanching bosselated lesion on left side of face. What is the treatment of choice in this child?

This child is suffering from po wine stain the most common vascular malformation. The treatment of choice of early and intermediate po wine satin is use of flash light pumped dye laser. The pulsed dye laser produces a light with a specific wavelength of 585 or 595 nanometers. This beam is selectively absorbed by red-pigmented material such as hemoglobin in the blood vessels of the lesion. This produces selective heat destruction of these structures, and the treated area becomes whiter. Po wine stain commonly appear on the face as flat patchy lesions that are reddish to purple in color. When present on the face, they are located in areas supplied by the sensory branches of the fifth (trigeminal) cranial nerve.
