Oncocytic variant of papillary renal cell carcinoma: A rare or underreported entity?

Papillary renal cell carcinoma (PRCC) is among the well-known malignant renal tumors, constituting 10%–15% of renal cell carcinomas (RCCs) and exhibits distinct clinical, pathological, and molecular features. [3] A 67-year-old male presented with pain in the left flank for 6 months, with a left renal mass in the midregion measuring 5 × 3 × 3 cm picked up on computed tomography of the abdomen. Many of the areas showed smaller single layer of nuclei [Figure 2]c, while other areas showed larger, Fuhrman grade 2 nuclei with pseudostratification [Figure 2]d. Focal areas showed nuclei arranged at the periphery of the cell with a reverse polarity [Figure 2]e. Areas of hemorrhage were noted.
