title: [Undifferentiated cutaneous angiosarcoma of the head: identification by the endothelial marker Ulex europaeus agglutinin I].
abstract: Cutaneous angiosarcoma of the head is a rare tumor of the elderly and can occur in an undifferentiated form without any clinical or histological signs of the vascular origin of this tumor. In these cases, the tumor can be identified by using endothelial cell markers, such as factor-VIII-related antigen and ulex europaeus agglutinin I, in an immunofluorescence technique or a peroxidase-antiperoxidase method. A 78-year-old patient is described who died within 18 months from such a tumor, which was diagnosed using the endothelial cell marker, ulex europaeus agglutinin I.
