title: Vasoformative tumor of the brain--immunohistology and ultrastructure.
abstract: A congenital vasoformative tumor in the brain of a 2-week-old boy manifested a variety of vascular spaces ranging from varices to solid cellular areas. The location of rod-shaped forms of reactivity to the immunoperoxidase stain for Factor VIII-related antigen corresponded with that of numerous Weibel-Palade bodies in the endothelial cell component of the tumor.
