#3921 Mixed neuroendocrine-non-neuroendocrine neoplasms of the rectum: A case report

Introduction: Mixed Neuroendocrine-Non-Neuroendocrine Neoplasms (MiNEN) represent roughly 1-2% of all colorectal malignancies. Given the rareness and heterogeneity of these mixed tumors, recognition and accurate diagnosis remain a challenge. In the absence of established guidelines, they are treated according to the standard of care for pure neuroendocrine carcinomas or adenocarcinomas from similar sites of origin.
