We report the cytological findings of a case of renal oncocytoma and a case of granular cell renal cell carcinoma. The renal oncocytoma showed monotonous populations of polyhedral or columnar cells with fine granular cytoplasm. They appeared as clusters (sheet, gland-like, or trabecular) or as single cells. Their cytoplasms showed distinct borders. The granular cell type of renal cell carcinoma consisted of round cells with somewhat variable N/C ratios. Most of the tumor cells appeared as single cells and had indistinct cell borders, occasional prominent nucleoli and unevenly distributed chromatin. The cytoplasmic granularity of the renal cell carcinoma was more extensive and thicker than that of the oncocytoma. We consider the difference between the two tumors to have originated from a difference in the distribution and density of mitochondria.
