BACKGROUND: Epithelioid hemangioendotheliomas (EHEs) of the head and neck region are uncommon malignant neoplasms that exhibit various biologic behaviors characteristic of both low- and high-grade malignancy. A subgroup of EHEs identified as "high-risk" EHEs because of their size and mitotic activity is associated with an unfavorable clinical course and poor prognosis. MATERIALS AND RESULTS: We describe the treatment of the first and, in terms of size, largest case of high-risk EHE arising from the neck. Despite wide excision, recurrence occurred 9 months after surgery, as had been expected. However, the tumor was found to express both vascular endothelial growth factor (VEGF) and VEGF receptor 2, indicating the potential of anti-VEGF therapy in the treatment of such cases. CONCLUSION: The finding that a high-risk EHE arising from the head and neck region is characterized by expression of VEGF and its receptor provides further support for the development of targeted molecular therapies. © 2012 Wiley Periodicals, Inc.
