REDONDO DE ORO, Katherine et al. Neuroendocrine tumor in the rectum simulating a benign neoplasm: case report and literature review. rev. colomb. cir. [online]. 2021, vol.36, n.4, pp.696-702.  Epub 17-Fev-2022. ISSN 2011-7582.  https://doi.org/10.30944/20117582.813.

Neuroendocrine tumors are defined as a heterogeneous group of neoplasms of epithelial origin from enterochromaffin cells disseminated throughout the body, and represent about 1% to 4% of all neoplasms. Its largest distribution is found in the gastrointestinal tract, where 75% of neuroendocrine tumors are located, being 27% of those in the rectum. We present the case of a 71-year-old patient who consulted for bright red blood per rectum, with no other associated symptoms, and was diagnosed with a grade 1 neuroendocrine tumor, which behaved as a benign lesion of the rectum.
