[Gastric stump cancer with osteoplastic metastases and microangiopathic hemolytic anemia].

In a case of adenocarcinoma in the anastomosis of a stomach resected by the Billroth II technique osteoplastic bone infiltration and microangiopatic haemolytic anaemia are described as paraneoplastic syndromes. Both phenomena open up a great deal of differential diagnoses for consideration. Even when the extended bone infiltration could already be observed, the primary tumor macroscopically in the stomach was not visible. Even an unremarkable B II anastomosis should be biopsied as a matter of routine.
