色素嫌性腎細胞癌の圧挫細胞診所見

抄録

We report a case of chromophobe renal cell carcinoma in a 39-year-old woman. The squash cytological specimen showed tumor cell clusters composed of large-sized polygonal cells with a low nucleocytoplasmic ratio. The cytoplasm was characteristically cloudy and reticular or eosinophilic granular. Occasionally, a perinuclear halo was visible. The nuclei were spherical and contained small nucleoli. The unique clinicopathological and molecular biological characteristics of chromophobe renal cell carcinoma make cytology a very useful tool for its correct diagnosis.
