Vascular tumors

Vascular tumors are a rare subset of vascular anomalies. These are classified based on their malignant potential or local destruction potential. Classification has been historically difficult and treatment recommendations are based on case series. The purpose of this chapter is to review the presentation, pathologic and imaging characteristics. Treatment recommendations are summarized based on the current literature. Congenital and infantile hemangiomas are covered separately in a separate chapter in this issue.
