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.
上皮样血管内皮细胞瘤（EHE）是一种罕见的血管肿瘤，其生物学行为不确定。大多数病例表现为软组织的单个病变，但也可能出现在肺、肝和其他部位。骨上皮样血管内皮细胞瘤是一种极为罕见的肿瘤，更常见于 20 至 30 岁的人群；其行为不确定，通常为单灶性，且更易累及下肢。在本工作中，我们介绍了一名 19 岁男性的临床、放射学和病理学表现，他患有累及 3 个椎体的多发性骨 EHE，并发生了肺转移。
