Angiosarcoma of common iliac vein

Abstract

Angiosarcoma is a rare malignant tumour of endothelial cells. Primary angiosarcoma of venous origin is extremely rare, and has a very poor prognosis. A 63-year-old woman with retroperitoneal mass underwent en bloc resection on a part of iliac vein followed by adjuvant radiotherapy. No recurrence was detected during 3 years of follow-up.

Deep Vein Thrombosis as an Initial Symptom of Malignant Tumor: A Case Report of Angiosarcoma in the Iliac Vein

“…Treatment for angiosarcoma is challenging in many cases, and the prognosis is generally poor [ 5 ]. However, there is a case in the iliac region that shows long-term survival by early diagnosis and combined therapy of surgical resection followed by radiotherapy [ 10 ]. Moreover, several recent reports have indicated the usefulness of novel therapeutic options, including neoadjuvant chemotherapy and immunotherapy [ 16 ].…”

“…Other common sites include the liver, bone, and lymph nodes. Although angiosarcoma can arise in any soft-tissue structure or viscera, tumors arising directly from the heart or major blood vessels are rare [5], as well as in vessels in the iliac region [7][8][9][10]. Interestingly, many cases of angiosarcoma from the iliac vessels exhibit thromboembolism as an initial symptom.…”
