Abstract:  Delineating the extent of capillary malformations in the operating suite can be challenging because of a variety of physiologic modifiers, including vasodilatation induced by anesthesia, reactive erythema, and filtering of colors with protective laser eyewear. The use of traditional surgical pens to mark the treatment field has limitations; we have found the use of a white eyeliner pencil to delineate lesions a contemporary technique that assists in identifying the target tissue intraoperatively.
