title: Angiosarcoma arising in an arteriovenous fistula site in a renal transplant patient: a case report and literature review.
abstract: Angiosarcoma in the setting of immunosuppressed renal transplant recipients is exceedingly rare. In this report, we describe the occurrence of angiosarcoma arising at an arteriovenous fistula site of a 39-year-old renal transplant recipient that clinically mimicked a thrombosed aneurysm. These tumors are histologically high-grade and clinically aggressive malignancies. They have a predilection for arteriovenous fistula sites. The literature on this uncommon entity is reviewed and possible histogenesis is discussed.
