Metastatic Epithelioid Angiosarcoma after Thrombolysis of an Occluded Ulnar Artery

Primary Aortic Epithelioid Angiosarcomas With Metastatic Disease Detected by 18F-FDG PET/CT

“…The pathological and the immunohistochemical examination revealed numerous large pleomorphic epithelioid cells with positive expression of ERG, CD34, and CD31, which supported the diagnosis of epithelioid angiosarcoma. Finally, based on the features of imaging and the pathology, the primary arterial epithelioid angiosarcoma with multiple metastases was confirmed 1,2 . Angiosarcoma is a malignant tumor derived from vascular endothelial cells or mesenchymal cells.…”

“…Finally, based on the features of imaging and the pathology, the primary arterial epithelioid angiosarcoma with multiple metastases was confirmed. 1,2 Angiosarcoma is a malignant tumor derived from vascular endothelial cells or mesenchymal cells. Primary aortic epithelioid angiosarcoma is extremely rare, [3][4][5][6] which can be mimicked as atheroembolic disease.…”

“…Primary aortic epithelioid angiosarcoma is extremely rare, 3–6 which can be mimicked as atheroembolic disease 7–9 . The pathological examination was very crucial for the diagnosis; however, a biopsy may be obtained from distant metastases or neoplastic embolism 1,2 . 18 F-FDG PET/CT is a useful imaging modality for differentiating arterial malignancy from arterial thromboembolism 10,11 .…”
