neys and the heart: A probable case of Stauffer syndrome in renal leiomyosarcoma with cava-atrial extension

Introduction: Abnormal liver function tests (LFts) are a common reason for referral to hospital although in some cases, no obvious hepatic pathology is found. Yet, they can indicate other disease processes not immediately obvious. A rare cause of cholestatic hepatic dysfunction is the paraneoplastic manifestation of malignancy. case report: Herein, we report a case referred with anicteric cholestatic hepatic dysfunction that was found to have a renal leiomyosarcoma with inferior vena cava (IVc) and right atrium extension. conclusion: the abnormal LFts were thought to be a paraneoplastic manifestation of the tumor as these were improving following surgical treatment.
