Basal cell carcinoma with intravascular invasion: A case report and review of the literature

Abstract

The significance of basal cell carcinoma (BCC) invading the intravascular space is unknown. We report a case of an infiltrative BCC on the scalp that showed evidence of both intravascular and perineural invasion. The tumor locally recurred in the bone marrow space 4.5 years following the initial procedure. Since recurrence and metastasis of BCC can be delayed for many years, we recommend long term follow-up for tumors showing aggressive features.
