We report two cases of tubulocystic renal cell carcinoma, a rare renal tumor the cytology of which has not been previously reported. Both aspirates were cellular and contained large sheets of cells with abundant granular cytoplasm, distinct cell borders and intracellular windows, distinct to prominent nucleoli, rare intracytoplasmic vacuoles, and rare nuclear grooves. Cells with variable amounts of cytoplasm were also arranged in small groups, some of which resembled spherules. The large sheets of cells with windows appeared specific for tubulocystic carcinoma; the spherules could easily be confused with a papillary renal cell carcinoma.
