De novo XXXX in a kidney allograft 20 years after transplant.

@entity1 @entity1358 @entity5
@entity1358 ( @entity1358 ) in a kidney allograft is rare. We report the successful diagnosis and treatment of a de novo @entity1358 in a nonfunctioning kidney transplant 20 years after engraftment. A 54-year-old @entity1 received a kidney transplant from his mother when he was 34 years old. After 10 years, chronic rejection resulted in graft failure, and the @entity1 became hemodialysis-dependent. Intravenous contrast-enhanced computed tomography (CT) for the evaluation of gastrointestinal symptoms revealed a solid 13   mm @entity5 in the kidney graft. The @entity5 was confirmed on ultrasound examination. This @entity5 had not been detected on a surveillance noncontrast CT scan. Needle biopsy showed that the @entity5 was an @entity1358 . Allograft nephrectomy was performed. Pathological examination showed that the @entity5 was a Fuhrman Grade 2 @entity1358 . XY-fluorescence hybridization analysis of the @entity1358 showed that the @entity5 cells were of donor origin. One year after the surgery, the @entity1 is alive and has no evidence of @entity5 recurrence. Regardless of whether a kidney transplant is functioning, it should periodically be imaged for @entity1358 throughout the recipient's lifetime. In our experience, ultrasonography or CT with intravenous contrast is better than CT without contrast for the detection of @entity5 in a nonfunctioning kidney transplant.
