case_images: (a) Gross specimen of angiosarcoma of the skull. (b) Microscopic picture which on H and E shows highly vascular tumor. There are many dilated irregular vascular spaces lined by pleomorphic atypical endothelial cells.(c) Immunohistochemistry (CD34): The atypical endothelial cells are highlighted by CD34
