GASPAR, Rui et al. Mixed Adenoneuroendocrine Tumor of the Rectum in an Ulcerative Colitis Patient. GE Port J Gastroenterol [online]. 2019, vol.26, n.2, pp.125-127. ISSN 2341-4545.  https://doi.org/10.1159/000489409.

Patients with inflammatory bowel disease present a higher risk of colorectal cancer, especially patients with a high degree of disease activity. Although rare, carcinoid tumors can also be associated with inflammatory bowel disease. Mixed adenoneuroendocrine tumor is defined as a neoplasm with dual differentiation (neuroendocrine and adenoma) with each component accounting for at least 30% of the tumor. We present a case of a mixed adenoneuroendocrine tumor in a patient with inflammatory bowel disease.

Keywords : Adenoneuroendocrine carcinoma; Ulcerative colitis; Endoscopic submucosal dissection.
