Highlights the need to consider sarcoma in the differential diagnosis of masses associated with vascular grafts and to investigate for distant metastasis.
Consider sarcoma in vascular graft mass differentials with metastasis evaluation; single case leaves open need for prospective validation.
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.
