Post operative gross specimens.
Gross specimen from a nephrectomy (CUT).
Atrophic kidneys with mulitple cysts. One cyst contains solid tissue (annotated).
This was a renal cell carcinoma.
Arrows indicate the tumor that developed within one of the cysts
Case Discussion
Even kidneys that no longer function can develop tumor within - a few renal cells remain enough to become neoplastic.
Imaging this type of patient can be a challenge given the limitations of contrast enhancement.
