[A Case of Pappilary Renal Cell Caircinoma which Responded Well to the Combination Therapy of Ipilimumab and Nivolumab --A CASE REPORT-].

We report a case of papillary renal cell carcinoma that responded well to the combination of ipilimumab and nivolumab. The patient was a 68-year-old male who was being followed up for a small left renal mass without treatment. Two years later, computed tomography (CT) showed enlarged cervical and para-aortic lymph nodes, and lymph node biopsy suggested metastases of the cancer.
