H.5.11 Kidney and part of the ureter with a tumour
- A specimen of a kidney with ureter from a 60 year old female who presented with abdominal pain and abdominal lump for two months.
- The abdomen had a ballotable lump on the right side.
- This is a markedly enlarged, destroyed kidney with markedly dilated renal pelvis and part of the ureter which is also dilated. (Weight 450gms)
- The surface of the kidney is irregular and lobular.
- Because the kidney is dilated, the cut surface does not show any resemblance to a normal kidney except at the periphery where there is minimal renal tissue (blue arrow)
- There are cystic areas separated by minimum renal tissue.
- At the junction between the dilated pelvis and the ureter there is an infiltrative tumour (red arrow).
- The histological assessment of this tumour revealed a Squamous cell carcinoma.
