We present 8 patients with primary tumors of the small intestine during the eleven year period from 1977 to 1987, and discuss about autopsy cases in Japan during the five year perid from 1981 to 1985. Eight cases were diagnosed by histological examination as follow: three cases of malignant lymphomas, one case of leiomyosarcoma and anaplastic carcinoma, two cases of lipomas and one leiomyoma. The symptoms of each cases were as follows: two cases of lipomas complained of abdominal fullness and slight low abdominal pain. A case of leiomyoma comlained of bloody stool. One case of anaplastic carcinoma complained of nausea, vomiting and severe abdominal pain. The diagnosis was established by radiological examination (Barium contrast study) 4 times. In 4 cases laparotomy was the diagnostic method because of acute abdomen. The tumor was almost located at the terminal ileum and at upper jejunal loop. A primary small intestinal tumor was rare, with a frequency of only 0.2∼0.4% of all the autopsy cases. In the autopsy cases the most frequent malignant tumors of the small intestine were adenocarcinoma, malignant lymphomas and leiomyosarcoma.
