Intravascular involvement of cutaneous squamous cell carcinoma.

We present a case of a 72-year-old man who was found to have intravascular invasion during Mohs micrographic surgery (MMS) of cutaneous squamous cell carcinoma (cSCC) on the left side of the forehead. The patient was subsequently treated with adjuvant radiation without evidence of disease recurrence. We present a case review to discuss treatment options for high-risk features of cSCC with the aim to assist in treatment guidelines.
