BK virus associated renal cell carcinoma: case presentation with optimized PCR and other diagnostic tests.
Polyomaviruses, including BK and JC viruses, have been associated with graft failure, but have not commonly been associated with malignancy. We present a case of renal cell carcinoma arising in an allograft kidney, in which the tumor and metastasis contain viral DNA. Tumor and biopsy specimens from this patient were examined with hematoxylin & eosin, immunohistochemistry (IHC) and in situ hybridization (ISH). The results were confirmed by real-time polymerase chain reaction (PCR) analysis with BKV primers. Other viruses including herpes simplex 1-2, cytomegalovirus (CMV), Epstein-Barr virus (EBV), and varicella zoster were not detected. The presence of BKV DNA in a renal cell carcinoma, including a metastatic focus, adds to the evidence that this virus may play a role in cancers of the kidney and urinary tract.
