Epithelioid hemangioendothelioma is a distinctive vascular tumor rarely involving bones. We report a case of epithelioid hemangioendothelioma in the cervical spine with angiosarcomatous areas. A 50-year-old female presented with dizziness while walking. A mixed sclerotic and osteolytic or destructive lesion was radiographically disclosed in her upper cervical vertebrae. Histologically, a laminectomy specimen exhibited areas of ordinary epithelioid hemangioendothelioma together with foci of more atypical epithelioid cell proliferation, closely resembling epithelioid angiosarcoma. This phenomenon has been exceptionally described in cases with skeletal lesions, which are typically of low-grade malignancy.

Epithelioid hemangioendothelioma (EH) is a rare, vascular neoplasm that can affect any age group and has been reported previously in sites including bone, liver, lung, breast, and brain. We describe a case of EH located in the mastoid, which appears to be the first report of EH in this site. The patient was 62 years old when they presented with dizziness and nausea. A suboccipital surgical approach was utilized to resect the tumor. After 18-month followup, the patient was symptom-free; however, imaging demonstrated a recurrence and the patient was taken back to the operating room for a resection. There is no evidence of recurrence after 8 years of followup. This paper aims to reinforce the need for a timely radical excision and aggressive clinical followup as the best hope for cure. Here, we describe an illustrative case and review the pertinent literature.
