Multicentric epithelioid hemangioendothelioma of bone. Report of a case with radiologic-pathologic correlation

Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor of uncertain biologic behavior. Most cases come out as a single lesion of the soft tissue but also may appear in the lung, liver, and other locations. Epithelioid hemangioendothelioma of bone is an extremely rare tumor and more prevalent in the second and third decades of life; its behavior is uncertain, it most commonly is unifocal, and it affects preferentially lower extremities. In this work, we present the clinical, radiologic, and pathologic findings of a 19-year-old man with a multicentric EHE of bone that involved 3 vertebrae and developed lung metastasis.
