UNASSIGNED: This report describes the morphological and immunohistochemical features of the first case of a @entity652 ( @entity652 ) of the urinary bladder infected with polyomavirus. The findings occurred in a female @entity1 , 6 months post cadaveric renal transplant. Voided urine cytology was positive for decoy cells. Renal transplant biopsy showed no evidence of @entity8999 allograft @entity8 . Cystoscopy demonstrated multiple erythematous patchy and nodular areas. These were found in the left and right posterior wall, and the right lateral wall toward the bladder neck, and were suspicious for either @entity32 or @entity5 . @entity1710 - @entity1711 stained sections showed a @entity652 with scattered pleomorphic nuclei demonstrating smudged chromatin and amorphous basophilic ground glass inclusions. Strong expression of polyomavirus large T antigen (SV40) and VP1 was seen in atypical lesional cells, consistent with cytopathic @entity6060 . Positive staining with @entity15529 supports the renal cell derivation of @entity652 . The findings in the present case suggest that @entity6060 , as an irritant of the bladder mucosa, contributed to the cytologic atypia of infected lesional cells but is not a pathogenic factor of @entity652 .
