Multi-system bleeding risk with a cutaneous angiosarcoma at an arteriovenous fistula site.

We present a case of angiosarcoma at an arteriovenous fistula site in a non-immunocompromised patient presenting as a soft tissue swelling with associated findings suggestive of lung malignancy, metastases and bleeding diathesis. This patient died of an otherwise unexplained subdural haematoma. Given the ability of this tumour to metastasise early and the poor prognosis of angiosarcoma without adequate resection, this needs to be considered early in any differential diagnosis of soft tissue masses near an arteriovenous fistula.
