title: [A case of multiple primary small intestinal adenocarcinomas].
abstract: A 62-year-old woman, with a past history of long-term non-steroidal anti-inflammatory drug use and gastric ulcer, was hospitalized for intestinal obstruction in April 2012. Two stenoses were identified in the ileum in association with small intestinal ulcers, and she underwent partial resection of the small intestine. Histologically, the two lesions were poorly differentiated adenocarcinomas; metastatic small intestinal cancer was suspected, but whole body examination revealed no other lesions. The final diagnosis was multiple primary small intestinal malignancies, necessitating additional resection of the small intestine in July. We report this case to raise awareness among physicians of the possibility of primary small intestinal cancer in patients with multiple small intestinal stenoses.
