Recurrent Left Renal Fossa Clear Cell Renal Cell Carcinoma With Pancreatic Tail Invasion Presenting as Intestinal Obstruction.

Distant renal cell carcinoma (RCC) metastatic disease is mostly seen in the lungs, bones, and lymph nodes. The incidence of local recurrences within the ipsilateral retroperitoneum (RFR) is very low. We report a case of a 79-year-old male with recurrent left renal fossa RCC with pancreatic tail invasion who presented with large bowel obstruction. To the best of our knowledge, no cases have been reported of recurrent left renal fossa RCC initially presenting as extrinsic large bowel obstruction.
