title: Primary vascular bone sarcomas. A clinicopathological and immunohistochemical study of two cases.
abstract: Two cases of primary vascular bone sarcomas are reported. The first case presented a rather slow clinical course and a non-aggressive histological picture and was classified as hemangioendothelioma. The second was a frankly malignant tumor, already metastatic at the time of diagnosis, which was classified as angiosarcoma. Views concerning the nomenclature and the behavior of primary vascular bone sarcomas are also discussed.
