摘要：We report a case of a 71-year-old male with multiple primary malignancies involving kidney and urinary bladder, combined with synchronous lymphoma. The patient was admitted to the hospital because of painless gross hematuria. Examination revealed tumor of the right kidney and papillary tumor in the urinary bladder and enlarged lymph nodes along aorta and inferior vena cava. Transurethral resection of bladder tumor (TUR), radical nephrectomy of the right kidney and retroperitoneal lymphadenectomy were performed. Pathohistologic evaluation, together with immunohistochemistry, gave the patient the final diagnosis of renal cell carcinoma (RCC), urothelial carcinoma of the urinary bladder and B- small cell Non-Hodgkin lymphoma (B-CLL).
