case_images: (A) A large number of papillary structures were observed under electron microscopy, and the surface of the papillary structure was covered with a large range of single layer of eosinophilic cells, and a strong eosinophilic cytoplasmic envelope was observed in the axis of the papillary structure. (B): The area indicated by the arrow shows a renal tumor, about 4cm*3cm in size. (C, D): CT often showed solid mass with lack of blood supply, clear boundary and mild enhancement.

case_images: (A) Under electron microscope, tumor cells showed cytoplasmic eosinophilic, low nuclear grade, and polar arrangement toward the papillary surface. (B): The area pointed by the arrow is the solid specimen of the kidney tumor (due to the open operation during the operation, the specimen display was not clear). (C-F): CT information of the tumor was shown from the sagittal plane and cross section respectively, and CT showed a solid mass lacking blood supply with clear boundaries and mild enhancement.
