case_images: Computed tomography identified a 14 x 11 cm cystic, space-occupying formation with many thick septae, which originated from anterior cortex of the left kidney and reached the level of pelvic inlet (Figure 1).
case_images: (a) Tumor tissue and intact parenchymal tissue (x40 hematoxylin-eosin). (b) The tumor cells with ovoid, round nuclei having coarse chromatin structure and a narrow eosinophilic cytoplasm (x400 hematoxylin-eosin).

case_images: Microscopically, tumoral cells had ovoid, round nuclei, coarse chromatin structure, and a narrow eosinophilic cytoplasm (Figure 2).
case_images: Immunohistochemical staining: (a) CD34 positive (x40), (b) CD99 positive (x100), and (c) staining showing a proliferative index of 1% with Ki-67 (x400).
