Abstract: Primary mesenteric neuroendocrine tumor is extremely rare. Here we describe 2 cases of this disease. Case 1 was a 66-year-old man with a working diagnosis of gastrointestinal stromal tumor or mesenteric tumor who underwent laparoscopic tumor resection. Immunohistochemically, the final diagnosis was primary mesenteric neuroendocrine tumor G1. There has been no recurrence as of 25 months after surgery. Case 2 was an 80-year-old man with a working diagnosis of gastrointestinal stromal tumor or mesenteric tumor who also underwent laparoscopic tumor resection. Immunohistochemically, the final diagnosis was primary mesenteric neuroendocrine tumor G1. This is recurrence-free as of 36 months after surgery. Several cases of primary mesenteric neuroendocrine tumor have been reported, but most have been treated with open surgery. To date, there has been only 1 case of primary mesenteric NET that was resected in a pure laparoscopic procedure. In all 3 cases (including our 2 cases), the largest tumor diameter was 4 cm. It appears that laparoscopic surgery can be used to treat primary mesenteric neuroendocrine tumor of small size (＜ 4 cm) with minimal invasion.
