Resumen
MUNOZ-CEDENO,, Rubén Gustavo et al. Right colon neuroendocrine tumor in a patient with ulcerative colitis: A case study. Rev. colomb. Gastroenterol. [online]. 2021, vol.36, n.4, pp.501-506. Epub 26-Abr-2022. ISSN 0120-9957. https://doi.org/10.22516/25007440.603.
Neuroendocrine colon tumors are relatively unknown compared with sporadic colorectal cancer; its incidence is low, and it is generally located in the cecum, sigmoid colon, and rectum. The existing relation between neuroendocrine tumors and ulcerative colitis is not frequently described due to the chronic inflammation that leads to neuroendocrine cell differentiation from multipotential cells in the dysplastic epithelium, which can be responsible for colorectal neuroendocrine carcinomas development. The study refers to the case of a patient of 57 years old with ulcerative colitis, abdominal pain, weight loss, and liquid diarrhea with mucus. Physical examination revealed a hardened lesion in the right colonic framework with the tomography of a neoplastic lesion in the ascending colon. When the patient was hospitalized, he developed an intestinal obstruction. A hemicolectomy plus ileostomy procedure was performed resulting in a large cell G3 neuroendocrine tumor in the ascending colon revealed in the biopsy. In this article, the aspects related to the pathophysiology, diagnosis, and treatment of the association of these two pathologies are reviewed in a practical way.
