Metastatic renal cell carcinoma associated with acquired cystic kidney disease 15 years after successful renal transplantation.
Renal cell carcinoma (RCC) is a relatively uncommon cancer in renal transplant patients. From 1968 to 1987, 101 cases of RCC of native kidneys have been reported to the Cincinnati Transplant Tumor Registry. We describe here a case of metastatic RCC associated with acquired cystic kidney disease (ACKD) 15 years after successful renal transplantation. The patient presented with a subcutaneous nodule, which led to discovery of a large primary tumor in the left kidney. ACKD was present in the atrophic right kidney. The reported cases of ACKD-associated RCC in renal transplant recipients were reviewed. Most of these cases are middle-aged men with a long posttransplant course, good graft function, and usage of azathioprine and prednisone as immunosuppressive agents. ACKD can develop or persist and progress to RCC many years after successful renal transplantation. Transplant patients with flank pain, hematuria, or other suspicious symptoms should have imaging studies of their native kidneys.
