Multiple Pyogenic Granulomas in Port-wine Stain after Laser Therapy / 대한피부과학회지

ABSTRACT

Pyogenic granuloma (PG) and port-wine stain (PWS) are vascular lesions that rarely occur in association. While PWSs are congenital capillary vascular malformations, PGs are acquired benign vascular proliferations. Although the pathogenesis of PG is unknown, many authors feel that they represent reactive hyperplasias, especially as they are often seen in response to trauma. We report the multiple pyogenic granulomas developed in a port-wine stain following Nd-YAG laser therapy.
