Intravascular leiomyosarcoma of the brachiocephalic region – report of an unusual tumour localisation: case report and review of the literature

Abstract

Abstract Background Intravascular leiomyosarcoma is a rare tumour entity originating from venous vessel structures and most frequently affecting the inferior vena cava. Case presentation A 69-year old patient presented with a biopsy proven leiomyosarcoma of the right supraclavicular region. Tumour resection and histological assessment verified the intravascular tumour origin arising from the internal jugular vein and extending into the surrounding soft tissue. Conclusion In the presence of a biopsy proven diagnosis of leiomyosarcoma the rare condition of an intravascular tumour origin has to be considered even without signs of venous stases. This may result in an altered surgical strategy. Microthrombembolism and pulmonary metastases may complicate the course of the disease.
