Core Tip
Core tip: Clear cell papillary renal cell carcinoma (ccpRCC) was recently established as a distinct type of epithelial neoplasm. Here, we report a case of partial nephrectomy for a ccpRCC detected during the routine follow-up a previously treated liposarcoma in a 70-year-old male patient. The patient received partial nephrectomy, the renal mass was pathologically diagnosed as ccpRCC, and immunohistochemistry revealed carbonic anhydrase 9 (CA9) expression. No recurrences or metastases were detected on follow-up imaging for 6 mo. This is the first report of partial nephrectomy for incidentally discovered CA9-positive ccpRCC.
