Chromophobe cell renal carcinoma is a recently established subtype of renal cell carcinoma. Herein we report a case of chromophobe cell renal carcinoma in a 67-year-old male patient who occasionally underwent computed tomography. In a microscopic study with hematoxylin and eosin stain, clear eosinophilic cytoplasm, and a moderately atypical nucleus were observed. And it was stained positively by Hale's colloidal iron. Ultrastructurally, the cytoplasm was filled with numerous microvesicles. From these results, this tumor was pathologically diagnosed as chromophobe cell renal carcinoma.
