AbstractPrimary malignant vascular bone tumors are unusual and include hemangioendothelioma, epitheloid hemangioendothelioma and angiosarcoma. Although few cases of primary bone angiosarcomas have been reported, those of femoral origin are even more infrequent. Such tumors diagnosis may be challenging due to their radiographic and histologic variety. We present a case of a 24-yearold woman with a subperiosteal diaphyseal angiosarcoma originating from the femoral bone and metastatic to the lung at the time of diagnosis. The clinical, histological and radiological features of this extremely rare lesion are presented.

Vascular Bone Tumors

The classification of vascular tumors of the skeleton can be thought of as a spectrum of disease including both benign and malignant entities. Chapter 60 focuses on the benign entities, hemangioma and epithelioid hemangioma. The term hemangioma refers to a collection of blood vessels and vascular spaces, perhaps better classified as a slow-flow vascular malformation. Epithelioid hemangioma is a rare and controversial entity that may be confused with its malignant counterpart, the epithelioid hemangioendothelioma. This chapter will describe the clinical, pathophysiological, and imaging features of these benign vascular bone tumors, with a brief mention of treatment strategies. Familiarity with the imaging appearances and characteristics of these entities is essential in order to guide clinical management and to avoid unnecessary investigation into clearly benign lesions.

Health Organization

The organization of vascular bone tumors can be thought of as a spectrum of disease including both benign and malignant entities. Chapter 61 focuses on the malignant tumors, which have elicited much controversy and debate. These include 2 vascular tumors of bone recognized by the World Health Organization: epithelioid hemangioendothelioma and angiosarcoma. Although there are no characteristic imaging features that would obviate the need for biopsy of these entities, they may present with multifocal bone lesions, which can suggest the diagnosis of a vascular tumor. This chapter will describe the clinical, pathophysiological, and imaging features of these malignant vascular bone tumors, with a brief mention of treatment strategies.

Conducting Research

Background: Our laboratory recently confronted this issue while conducting research with undergraduate students at the University of Waterloo (UW). Although our main objective was to examine cognitive and genetic features of individuals with schizotypal personality disorder (SPD), the study protocol also entailed the completion of various self-report measures to identify participants deemed at increased risk for suicide. Aims and Methods: This paper seeks to review and discuss the relevant ethical guidelines and legislation that bear upon a psychologist’s obligation to further assess and intervene when research participants reveal that they are at increased risk for suicide. Results and Conclusions: In the current paper we argue that psychologists are ethically impelled to assess and appropriately intervene in cases of suicide risk, even when such risk is revealed within a research context. We also discuss how any such obligation may potentially be modulated by the research participant’s expectations of the role of a psychologist, within such a context. Although the focus of the current paper is on the ethical obligations of psychologists, specifically those practicing within Canada, the relevance of this paper extends to all regulated health professionals conducting research in nonclinical settings.

Whole-body scintigraphy with both 99mTc-phosphonate and 67Ga was performed on 92 patients suspected of primary bone tumors. In 46 patients with primary malignant bone tumors, scintigraphy with 99mTc-phosphonate disclosed the primary tumor in 44 cases and skeletal metastases in 11, and 67Ga scintigraphy detected the primary tumor in 43 cases, skeletal metastases in 6 cases and soft-tissue metastases in 8 cases. In 25 patients with secondary malignant bone tumors, bone scintigraphy visualized a single lesion in 10 cases and several lesions in 15 cases, and 67Ga scintigraphy detected the primary tumor in 17 cases, skeletal metastases in 17 cases and soft-tissue metastases in 9 cases. In 21 patients with benign bone disease positive uptake of 99mTc-phosphonate was recognized in 19 cases and uptake of 67Ga in 17 cases. It is concluded that bone scintigraphy should be used in patients suspected of primary bone tumors. If malignancy is suspected, 67Ga scintigraphy should be performed in addition.
