The smaller lesion (0.5 cm): the figure shows a solid growth pattern and perinuclear cytoplasmic clearing. (a). In the box: The tumor contains a population of large, round to polygonal cells with well-defined cell borders and amphophilic, pale basophilic to foamy cytoplasm; nuclei are typically hyperchromatic, elongated and grooved with an irregular nuclear membrane. These features suggest chromophobe renal cell carcinoma; alternatively the lesion may represent a focus of tubular oncocytosis and a precursor of another oncocytoma; the two types of lesions are in any case strictly correlated [43, 44](b) (Hematoxylin eosin stain)
