A 57-year old man was referred to the Urology Department due to gross hematuria; abdominal ultrasound revealed an unspecific solid tumor of the left bladder wall. Ultrasound, transurethral resection of the bladder mass with subsequent histological analysis, thoracic and abdominal computed tomography-scan and brain magnetic resonance imaging were performed. He was diagnosed with a bladder metastasis of clear cell renal cell carcinoma (RCC) with concomitant bone, pulmonary, and cerebral metastatic disease of a primary RCC of the right kidney.
Management: Transurethral resection of the bladder mass, cerebral and bone radiotherapy, removal of the primary tumor, targeted systemic therapy with mTOR followed by tyrosine kinase inhibition.
Keywords: bladder metastasis; hematuria; renal cell cancer; transurethral resection.
