Abstract:
Bladder angiosarcoma is an extremely rare neoplasia whose aggressive biological behavior follows that of other angiosarcomas. The second case of primary angiosarcoma of the bladder is reported pointing out the immunohistochemical characteristics of these neoplasias. Using immunoperoxidase staining techniques, Ulex lectin has proved to be a more sensitive marker for endothelial cells than factor VIII-related antigen, and it should be used as an additional marker for endothelial cell-derived tumors.
