Primary neoplastic vascular lesions of bone are rare, and include haemangiomas, haemangioendothelioma, epithelioid haemangioendothelioma and angiosarcoma. These lesions may be multicentric, and when they involve bone are typically intraosseous and lytic. Radiological findings are not always specific. We report a case of haemangioendothelioma localised to the subperiosteum of the femur, a site not previously described for this lesion. The nomenclature for vascular neoplasms in bone is discussed.
