Clinical Presentation The presenting signs and symptoms include hematuria, abdominal pain, and a flank or abdominal mass. This classic triad occurs in 10–20% of patients. Other symptoms are fever, weight loss, anemia, and a varicocele (Table 90-4). The tumor can also be found incidentally on a radiograph. Widespread use of radiologic cross-sectional imaging procedures (CT, ultrasound, MRI) contributes to earlier detection, including incidental renal masses detected during evaluation for other medical conditions. The increasing number of incidentally discovered low-stage tumors has contributed to an improved 5-year survival for patients with renal cell carcinoma and increased use of nephron-sparing surgery (partial. | Chapter 090.

A spectrum of paraneoplastic syndromes has been associated with these malignancies including erythrocytosis hypercalcemia nonmetastatic hepatic dysfunction Stauffer syndrome and acquired dysfibrinogenemia. Erythrocytosis is noted at presentation in only about 3 of patients. Anemia a sign of advanced disease is more common.
