Primary Neuroendocrine Tumor of Mesentry-A Rare Case Report

Primary neuroendocrine tumor of the mesentery is very rare. More than 90% of gastrointestinal neuroendocrine tumors are located in the appendix, small intestine and rectum. We report a case of 70yr old male with very rare primary neuroendocrine tumor of the mesentery without any evidence of any primary tumor site. The only symptoms were persistent pain of the abdomen lasting for one year. The mass was radically excised during laparotomy. CT and MRI were useful to clarify the site of origin of the tumor but final diagnosis was based on histological findings.
