Primary renal angiosarcoma

An older male patient with a history of tachycardia treated with atenolol presented to an outside hospital on 22 February 2017 with acute right flank pain. He had a CT scan which revealed a large right renal mass with acute haemorrhage. He was initially managed with interventional radiology guided embolism on 25 February 2017 due to the ongoing bleeding and haemodynamic instability. He was then transferred to our institution. He underwent right radical nephrectomy on 13 March 2017. His pathology revealed a 12.5×6×4.5 cm mass consistent with angiosarcoma of the right kidney with negative margins. Final pathology was pT2b with extension of the mass into the renal vein and perirenal adipose tissue. He was discharged soon after surgery. He was recommended to undergo adjuvant chemotherapy.
