Multifocal Basal Cell Carcinoma Developing in a Facial Port Wine Stain Treated with Argon and Pulsed Dye Laser: A Possible Role for Previous Radiotherapy

Abstract

This case of a clinically indistinct multifocal basal cell carcinoma arising within facial port wine stain was most likely due to previous radiotherapy treatment as a child, rather than laser treatment. Careful treatment history should identify such patients who should be followed-up for development of skin cancer.
