Abstract

BackgroundAngiosarcoma is a rare malignant tumor, originating from vascular endothelial cells, accounting for approximatively 1–2% of soft tissue sarcomas. It is characterized by a rapid proliferation and high metastatic potential. Some cases of angiosarcoma are described in association with vascular prosthesis, orthopedic devices and foreign bodies. Hereby, we report a case of a patient treated with the endovascular placement of a PTFE aorto bis-iliac prosthesis for aortic aneurysm, who developed a graft-related angiosarcoma with bone and peritoneal localizations. The peritoneal “sarcomatosis” led to an acute presentation with hemoperitoneum and anemia. We perform a thorough review of the literature summarizing the description of similar cases, their epidemiology and the possibilities for treatment.Case presentationAn 84-year-old male with a history of abdominal aortic aneurysm endovascular repair presented to our emergency department complaining with low back pain radiating to the left limb. He underwent a type II endoleak embolization of the aneurysmal sac nine days before. During hospitalization he underwent a spine MRI which documented a vertebral alteration of non-univocal interpretation. Vertebral biopsy was performed revealing groups of cells of uncertain nature. He lately underwent percutaneous L2–L4 arthrodesis. Forty-two days after admission, he developed acute anemia. Emergency laparotomy revealed a massive hemoperitoneum and actively bleeding peritoneal nodules. Abdominal packing was performed, and several nodules were sent for definitive histological examination. After surgery, he developed progressive and severe hypovolemic shock and expired on postoperative day 5.ConclusionsAngiosarcoma associated with foreign bodies, especially vascular prosthesis, is a very rare entity. In patients who have a history of prosthetic vascular graft placement that present with lumbar pain, osteolytic changes at radiologic imaging or the development of ascites, angiosarcoma should be considered in the differential diagnosis. Despite the poor prognosis, a prompt diagnosis might give access to an adequate treatment planning, with the aim for disease control and increased survival.
