She was operated on for clear cell renal cancer in the right kidney and was treated by total nephrectomy. Successive computed tomography controls were carried out, initially 6 months after surgery and subsequently each year. Three years after the right nephrectomy a hypervascular nodule was detected in the pancreatic body, which suggested the differential diagnosis between a metastasis and a primary pancreatic neuroendocrine tumour (<a class="elsevierStyleCrossRefs" href="#fig0005">Figs. 1 and 2</a>).</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><p id="par0035" class="elsevierStylePara elsevierViewall">As a result of these findings, a study with complete hormonal markers and a scan were performed to rule out the primary pancreatic neuroendocrine tumour.

On suspicion of pancreatic metastases due to the previous surgical background of the patient, a first diagnostic possibility was indicated to be the performing of a corporocaudal pancreatectomy with open splenectomy. During the operation and with use of a scan, a tumour of approximately 1<span class="elsevierStyleHsp" style=""></span>cm in diameter was confirmed in the body of the pancreas (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>), which was later observed as a surgical specimen (<a class="elsevierStyleCrossRef" href="#fig0020">Fig. 4</a>).</p><elsevierMultimedia ident="fig0015"></elsevierMultimedia><elsevierMultimedia ident="fig0020"></elsevierMultimedia><p id="par0040" class="elsevierStylePara elsevierViewall">The postoperative period was free from any complications and the patient was discharged 6 days after the operation.
