A rare cause of tumor ileus, neuroendocrin mixed non neuroendocrin neoplasm (MINEN): case report

Abstract

Mixed neuroendocrine-nonneuroendocrine neoplasias (MiNEN) are rare neoplasias with unknown pathophysiology. In order to make this diagnosis, neuroendocrine cell and adenocarcinoma components must be at least 30% each in the tumor. They are rarely seen in the colon. In this case, we aimed to present 2 cases who were operated due to tumor ileus and whose postoperative pathology results were compatible with MiNEN.
