title: [Differential diagnosis of Crohn disease: segmental intestinal metastasis of breast and stomach cancer].
abstract: Metastatic malignancies are able to imitate the radiological or intraoperative findings of Crohn's disease. Being of great importance in individual cases, the manifestation of intestinal metastases mimicking Crohn's disease is analysed. Since 1960 world literature has reported intestinal metastases simulating Crohn's disease in 19 patients. Primary tumours were breast cancer (13 patients), gastric cancer (5 patients) and unknown primary focus (1 patient), in which even postmortem examination failed to reveal the site of primary cancer. 12 (67%) of 18 specified patients showed metastatic infiltration of the terminal ileum. Long segments of narrowing were found in all patients. Since specific signs such as age, sex, localization or macroscopic appearance to differentiate Crohn's disease from metastatic tumour spread are lacking, a histological examination is necessary to establish the correct diagnosis. The median survival time was approximately one year following the intestinal tumour spread.
