Bone vascular endothelial cell tumor

In 1943, Stout named malignant vascular tumors as hemangioendothelial cell tumors. Later, the histological classification and nomenclature were very confused. Many names have been used, and they have gradually been unified, and they are called bone vascular endothelial cell tumors. Bone vascular endothelial cell tumor is recognized as an intermediate or indeterminate tumor between osteoangioma and osteoangiosarcoma, which is a benign and malignant tumor. It is a low malignant tumor with diffuse infiltration and growth but not metastasis.
