Abstract
A case of primary cancer of the ileum causing perforative peritonitis is described. A 72-year-old woman complaining of lasting abdominal pain for a year had occult blood of stool and anemia. The patient was suspected of having a tumor of the uterus because a tumor mass was displayed in the oral and back side of the urinary bladder by the echo tomography on June 22, 1990. On July 1, 1990 emergency lapalotomy was performed because of panperitonitis due to perforation of the tumor. The tumor in the ileum was located at 6 cm oral from the ileocecal valve, protruded into the mesenteric side, and adhered to the urinary bladder, rectum, and right ovary and uterine tube. The ileocecal region was resected with the right ovary and uterine tube. In the gross appearance, the tumor was a circumferential, ulcerating and circumscribed lesion without stenosis. The ulcer bottom of the tumor expanded (aneurysm-formed) and perforated. Pathologically the tumor was well differentiated adenocarcinoma with mucin (s3 (right ovary and uterine tube), n0, P0, H0).
