Abstract

<p>A 71-year-old female visited our hospital due to a tumor in front of the pancreas detected on abdominal US. The hypoechoic tumor was 30 mm in size and infiltrated the accessory right colic vein. The primary mesenteric tumor was suspected to be gastrointestinal stromal tumor or neuroendocrine tumor (NET). Laparoscopic tumor resection was performed. In laparoscopic findings, the tumor had no anatomical continuity with the mesentery of the transverse colon, and the tumor artery was a branch from the right gastroepiploic artery. Thus, the postoperative pathological diagnosis was NET derived from the gastrocolonic mesentery. In immunostaining, tumor cells were positive for chromogranin A, synaptophysin and CD56, and Ki-67 was 1%. These findings show that the tumor was NET G1. Gastrocolonic mesentery NET is extremely rare. Laparoscopic resection was feasible and the visibility was sufficient to see the anatomical continuity with the surrounding organs. We report this extremely rare case of gastrocolonic mesentery NET with a literature review.</p>
