(A, B) Computed tomography revealed a slightly high-density nodule at the lower pole of the left kidney for case one, with a diameter of about 2.5 cm and a CT value of 57 HU on plain scan with no obvious strengthening. (C, D) CT demonstrated a 1.6x1.3 cm round high-density nodule in the right kidney of case 2 with a CT value of about 80HU on plain scan. No enhancement after intravenous administration of contrast was noted.

Both the pathological manifestations of the tumors from the aforementioned two patients were consistent with typical PRNRP. The HE staining showed papillary or tubular structures, the surface was covered with a monolayer of eosinophils, the cytoplasm was granular, with small nuclei away from the cytoplasmic top of the basement membrane. The immunohistochemical phenotype was GATA3 (+), vimentin (-) (A, B: Case 1 C, D Case 2).
