Renal tumors comprise a wide spectrum of benign and malignant tumors. The important prognostic factors in renal cell carcinoma include pathological stage, tumor grade, morphological type, sarcomatoid/rhabdoid differentiation, and tumor necrosis. Therefore, the pathologist needs to be fully aware of how to gross nephrectomy specimens to be able to accurately provide the above prognostic information while reporting adult kidney tumors. With the advent of nephron-sparing surgeries, due diligence should be exercised to assess and sample the parenchymal surgical margin. This article discusses the approach to grossing nephrectomy specimens, elaborates the significance of every step, and also sheds light on the importance of clinical and radiological information in providing a holistic approach to the diagnosis and staging of adult renal tumors.
