| Abstract: | We report a case of renal cell carcinoma within a simple renal cyst in the lower pole of the right kidney. Excretory urography showed a mass and ultrasonography revealed multiple renal cysts with a solid component arising from the wall in 1. This finding also was visualized by computerized tomography. Analysis of the cystic fluid showed a high cholesterol level but negative cytological results. At operation a 7 mm. tumor arose from the wall of the cyst. Histopathological examination showed grade 3 renal cell carcinoma with an aneuploid deoxyribonucleic acid content. |
