Late metastases to the pancreas from resected renal cell carcinoma masquerading as multiple endocrine neoplasia

We report the case of 58-year-old gentleman with pancreatic masses, possibly of neuroendocrine origin, with the history of renal carcinoma, primary hyperparathyroidism and pituitary cyst. Histological analysis after pancreatectomy revealed metastases from renal cancer. This unusual case illustrates the challenging differential diagnosis between multiple endocrine neoplasia (MEN) syndrome and metastatic renal cell cancer.
