Malignant fibrous histiocytoma of the aorta complicated by anuria

Abstract

Tumors of the aorta have been reported infrequently in the literature. We report a case of a 63-year-old woman diagnosed with malignant aortic fibrous histiocytoma (also known as fibroxanthosarcoma). She was referred to us with suspected occlusion of the right renal artery in a single functioning kidney, with a clinical picture of anuria during the previous 48 hours. We also review 31 previously published cases in the literature.
