摘要

Clear cell papillary renal cell carcinoma(ccpRCC)was recently established as a distinct type of epithelial neoplasm by the International Society of Urological Pathology Vancouver Classification of Renal Neoplasia.Here,we report a case of partial nephrectomy for a ccpRCC detected during the routine follow-up of a previously treated liposarcoma in a 70-year-old male patient.The patient was referred to the urology department for a right-sided renal mass(size:2 cm)detected during routine annual imaging follow-up for a malignant right inguinal fibrous histocytoma and liposarcoma that had been diagnosed 6 and 4 years earlier,respectively,and treated with surgery and adjuvant radiation therapy.Following 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 months.This is the first report of partial nephrectomy for incidentally discovered CA9-positive ccpRCC.
