A 61-year-old man consulted a nearby doctor with the chief complaint of lassitude in June 2010. Blood tests revealed a hemoglobin level of 37 g/dL The observation of significant anemia resulted in a full medical workup. On computed tomography (CT) findings a large mass (17×10 cm in diameter) was found in the abdominal region. The lumen was distended with accumulation of air and fluid. In addition, I continued with a bladder wall, but did not recognize the abnormality that was apparent to a bladder lumen. There was no evidence of ileus. A diagnosis of appendix cancer or sarcoma was made preoperatively. During surgery, the bladder was observed to have some permeation, but the bladder wall contained a lesion of small intestinal origin with only slight permeation. The neighboring small intestine was surrounded by the tumor, with 3 sites of Penetration. Histopathologic diagnosis indicated a high-risk gastrointestinal stromal tumor (GIST) with mitotic figures (44/50 high power fields) In accordance with the recommended guidelines, imatinib was administered for 1 year. Two sites of recurrences were observed by CT after discontinuing imatinib. A second operation was performed without increase because of the absence other lesions Separate lesions in the sigmoid colon and jejunum were removed surgically. The tumor in the sigmoid colon was a lesion with high denaturation for mesenchymal system tumor such as GISTs by pathologic diagnosis. The lesion in the small mesentery was a suture granuloma. In this case, the combination of surgical management with chemotherapy resulted in good quality of life with no recurrence despite the presence of a high-risk GIST.
