Abstract
We report a rare case of small intestinal cancer with a propensity for extramural growth that was diagnosed before surgery. A 61-year-old woman was admitted to our hospital because of melena. Small intestinal cancer with extramural growth propensity was diagnosed by various clinical and histological examinations. Examinations revealed that it was located about 10 cm proximal to Bauhin's valve and showed Borrmann 2 type appearance. The histological diagnosis was moderately differentiated adenocarcinoma of the small intestine. Distal ileal resection and right hemicolectomy with group 3 lymph node dissection were performed, and adjuvant chemotherapy was added after the operation. Ileal cancer is very uncommon among malignant tumors of the gastrointestinal tract, and few cases are diagnosed correctly before surgery. Therefore we suggest more aggressive investigation in cases of small intestinal cancer to improve curability.
