● Assessment of surgical margins often performed in partial nephrectomy cases (Urology 2006;67:923, Scand J Urol Nephrol 2005;39:222)
● However, clinical significance may be limited, as only rare patients harbor residual disease in a follow-up radical nephrectomy specimen or repeated partial resection of margin
● Recurrence due to positive margin is uncommon (Urology 2011;77:1400, J Urol 2005;173:385)
● Solid renal mass in unusual setting, synchronous renal and extrarenal masses, cystic renal lesions, multiple renal masses, solid mass in diffusely cystic kidney (Arch Pathol Lab Med 2005;129:1585)
● However, no consensus exists (J Urol 2008;179:461)
● Cystic and spindle cell tumors are often misdiagnosed
● Clear cell renal cell carcinoma can be confused with inflammatory lesions, particularly those that contain foamy histiocytes
