Primary urinary bladder angiosarcoma with ascites

Abstract

Non-urothelial tumors of the urinary bladder are rare. Sarcomas constitute less than 1% of all malignant neoplasms and angiosarcomas comprise 2% of all sarcomas [1]. We report a case of a 69-year old male with history of a low-grade prostatic adenocarcinoma for which he underwent external beam radiation therapy in 1/2010. He presented to the ER in 9/2015 with an abdominal distension and urinary retention and was found to have malignant ascites, hydronephrosis and a urinary bladder mass. Pathologic evaluation of the ascites and urinary bladder tumor revealed metastatic epithelioid angiosarcoma. Since the patient presented with an advanced stage inoperable disease, chemotherapy was initiated shortly thereafter. Unfortunately, the patient became septic and died 6 weeks following the original diagnosis. Keywords: Urinary bladder neoplasms, Epithelioid angiosarcoma, Postirradiation-associated sarcoma
