Pancreatic late recurrence of bilateral renal cell carcinoma after conservative surgery.

The appearance of solitary late metastases of renal cell carcinoma has seldom been documented. A female patient, who 13 years previously underwent left radical nephrectomy and right lower polar resection for bilateral simultaneous renal cell carcinoma, presented with a solitary pancreatic metastasis which was successfully treated with pancreaticoduodenectomy. The major points of interest of this report are the occurrence of a primary bilateral tumor, the initial treatment with conservative surgery and the site of late recurrence. The diagnostic and prognostic implications of late metastases of renal tumors are discussed.
