Fifteen patients, 10 males and 5 females, between 10-27 years age with different benign vascular skin lesions i.e.haemangioma (3) and lymphangioma circumscriptum (2) were taken up for this study. The lesions in all the patients were vaporized/excised with the indigeneously developed carbon dioxide laser. The patients were evaluated at 1,2,4,8 and 12 weekly visits to assess the overall response to the treatment and the side effects. All the patients responded to the treatment. The patients with granuloma pyogenicum showed excellent response with complete disappearance of the lesions while the patients with haemangiomas, lymphangio-haemangiomas and lymphangioma circumscriptum improved by 70-90%. Transient hypopigmentation and mild scarring were seen in all the patients except in patienls with granuloma pyogenieum. There were no other significant side effects in any of the patients.
