Neuroendocrine tumor, Rectal neoplasm, PolypAbstract
Diagnosis of rectal neuroendocrine tumor (NET) has increased due to the implementation of colonoscopies as a screening method. Most rectal NETs are less than 1cm at diagnosis time, confined to the submucosa, and well differentiated. They generally have a benign course and are treated mainly using endoscopic methods. Metastases are rare and depend on tumor size and other factors such as submucosal invasion, lymphatic spread, and histologic classification, which will determine the prognosis and treatment. We present a case of a rectal neuroendocrine tumor as a polyp during routine endoscopic screening and a review of the current literature.
