Squamous cell carcinoma arising within a facial port-wine stain treated by mohs micrographic surgical excision.

摘要

Nonmelanoma skin cancer arising within facial vascular malformations that have previously been treated with superficial ionizing radiation has-, been previously reported. Excision of tumors from vascular malformations may pose the difficulty of clinically determining the tumor margins. Mohs micro-graphic surgery should be considered with the aim of producing tumor-free surgical margins and tissue conservation. This is especially important in esthetically sensitive areas.
