Angiosarcoma of the skull base is exceedingly rare, and diagnosis is based on the identification of abnormal vascular proliferation and the invasive nature of tumour. Immunohistochemical positivity for ERG (nuclear expression) and CD31 confirms the vascular origin of the lesion. These markers will also be expressed by the vascular component of angiofibroma and haemangiopericytoma, although the associated stromal components will not stain [73–77].
