[Multiple smooth colon stenosis in 76-year-old female patient].

Differential diagnostic aspects of colon stenoses are discussed using the example case of a female patient presenting with multilocular colon metastases, who had lobular breast cancer 9 years previously. Typical is linitis plastica, which can indicate tumorous infiltration not only of the stomach, but also of the large intestine. Other endoscopic imaging and histological studies may, however, fail. The pathologist requires the anamnestic data relating to the breast cancer for exact assignment of the tumorous infiltration.
