Primary Extrarenal Type 2 Papillary Renal Cell Carcinoma: A Case Report.

Type 2 papillary renal cell carcinoma (PRCC) is a malignant tumor originated from renal tubular epithelial cells. Here we present a rare case of extrarenal type 2 PRCC which is located at the right lateral side of the retroperitoneal inferior vena cava. No suspicious lesions were detected in the bilateral kidneys. The diagnosis was confirmed by histopathological examination after complete excision of the tumor. No recurrence was observed in 5 months of follow-up after surgery.
