[Malignant and semimalignant small intestinal tumors--illustrated by two cases].

The authors review two cases of small bowel tumor. The first patient was operated electively with small bowel carcinoid causing multiplex liver metastases. The second patient was admitted because of massive gastrointestinal bleeding. After some diagnostic procedures bleeding of the small intestine was diagnosed. Urgent operation was performed and a bleeding jejunal tumor was removed. Gastrointestinal stroma cell tumor of the small bowel was found at histology. In connection with the patients some points about malignant small intestine tumors are analysed based on literature.
