Abstract
We describe a case of retroperitoneal angiosarcoma in association with an aorta-bifemoral
Dacron graft. Surgery was not performed and the patient died. At autopsy, a local
extensive, high-grade angiosarcoma was confirmed and a left pulmonar metastase was
found. A sarcoma should always be considered in the differential diagnosis of any
mass associated with vascular grafts, and an extensive investigation of possible and
unsuspected distant metastasis is mandatory in all cases.
