A 66-year-old Black man in the United States with hypertension indicates that he has been having pain in his back, which he thought was a pulled muscle. However, he claims that the pain hasn't changed even with the use of massage and a heating pad. He also states that he has been running occasional fevers but had no other signs of infection.
His body mass index is 40 kg/m2. Physical examination identified a palpable mass on his left flank and the presence of scrotal varicocele. Laboratory results include microscopic hematuria, anemia, and hypercalcemia. His hemoglobin level is 11 g/dL, neutrophil count is 8.5 x109/L, and platelet count is 350,000/µL.
CT shows a single solid mass in his kidney.
