Bone tumors are a rare and heterogeneous group of neoplasms that occur in the bone. The
diversity and considerable morphologic overlap of bone tumors with other mesenchymal …

Vertebral hemangiomas (VHs) are a frequent and often incidental finding on computed
tomography (CT) and magnetic resonance (MR) imaging of the spine. When their imaging …

Primary bone tumors are uncommon and this has certainly contributed to the scarcity of data
about their relative frequency, and to the limited understanding of the risk factors. Overall …

Epithelioid hemangioma of bone is a locally aggressive vascular neoplasm. It can be
challenging to diagnose because of the wide histological spectrum, which can make it …

Recent molecular discoveries have refined vascular bone tumor classification. To
investigate the clinical relevance of these refinements, we reviewed all cases of primary …

The classification of vascular tumors of bone has been under debate over time. Vascular
tumors in bone are rare, display highly overlapping morphology, and, therefore, are …

Primary intraosseous hemangiomas are benign, vascular malformations that account for
approximately 1% of all primary bone neoplasms. These tumors are mostly found in …

Histologically VHs are not considered vascular neoplasms, but rather hamartomas or
malformation of the microcirculation. Basing on the predominant type of vascular channel …

Primary vascular tumors of bone are a heterogeneous group of neoplasms, ranging from
benign hemangiomas to frankly malignant epithelioid hemangioendotheliomas and …

Epithelioid vascular neoplasms of the bone are classified by the World Health Organization
(WHO) into only two tiers: low-grade epithelioid hemangioma (EH) and a more malignant …
