Primary angiosarcoma of the femur: a diagnostic dilemma with a rare bone tumour

We describe a rare case of high-grade primary angiosarcoma of the proximal femur in a 66-year-old man that proved fatal secondary to pulmonary metasta ses. The difficulties experienced in histological and immunohistochemical d iagnosis of these tumours, and the resultant need for a high index of suspi cion by surgeons in general and orthopaedists dealing with bone tumours in particular, is emphasized, as is the need for multidisciplinary management.
