Intimal sarcoma arising from the common iliac artery presenting with artery occlusion : a case report and literature review

We present a rare case of intimal sarcoma arising from the common iliac artery in an 82-year-old man who presented with intermittent claudication. He had undergone endovascular therapy with self-expanding stents to both iliac arteries that had occluded soon after placement. After salvage bypass grafting, a diagnosis of intimal sarcoma with angiosarcoma phenotype from the iliac artery was made. Further bypass graft surgery relieved symptoms temporarily. However, the tumor progressed and the left limb became ischemic. The chemotherapy of eribulin did not prevent tumor progression. The patient died of the disease 20 months after the first surgery.
