diagnosis of cancer in gastric biopsies or resection specimens. The histopathological slides of both renal and gastric cancer probes, and the clinical presentation, treatment and outcome of affected patients, were reassessed. RESULTSTwelve patients with primary gastric cancer, one with local RCC recurrence affecting the antrum and five with clear cell RCC (three men and two women; mean age 73 years, range 65-83) with haematogenous cancer spread to the stomach were detected. The mean (range) time to gastric metastasis was 6.9 (1.7-13.1) years. There were metastases to other organs, most often the lung, in all patients.

pT3 sub-classification was significantly associated with patient outcome. In contrast, pT2 and pT4 sub-classification did not show clinical significance.

Intussusception is a rare clinical finding in adults. Most cases occur in the distal small bowel or large intestine. We report the case of a 65-year-old woman with known non-small-cell lung cancer (NSCLC) who presented with acute abdomen and ileus-like symptoms. Abdominal computed tomography suggested ileocecal intussusception. The patient underwent right hemicolectomy and the histopathological workup showed ileal NSCLC metastasis as the lead lesion of intussusception. The classic triad of cramping abdominal pain, bloody diarrhea and a palpable tender mass, which is present in the majority of pediatric patients, is only infrequently observed in adults. Thus, symptoms are often nonspecific and the clinical presentation may be inconspicuous. Because of the large proportion of structural anomalies, adult intussusception requires definitive treatment, of which surgical resection is the treatment of choice. In patients with colocolonic or ileocolonic intussusception, malignancy should be considered and therefore en bloc resection rather than reduction is the recommended surgical technique, whereas cases of enteric intussusceptions may be reduced by limited resection of the small intestine.
