Obscure Gastrointestinal Bleeding Due To A Neuroendocrine Tumor. About a case

Abstract Text We present a case of a 78-year-old male, from Portugal, with a history of laparoscopic sigmoidectomy for colorectal neoplasm in 2018, as well as, focal epilepsy, colonic diverticulosis, hepatic hemangioma, ischemic heart disease with by-pass and a biological aortic prothesis. We met the patient in 2018 with a first episode of obscure gastrointestinal bleeding. A complete endoscopic study was conducted at that time, revealing multiple erosions in the distal jejunum and proximal ileum as the cause of the bleeding. In 2023, he had another episode of melena. It was decided to repeat the capsule endoscopy that suggested a neoplastic origin of the bleeding, and a decision was made for surgical resection. Ultimately, the histological study confirmed the diagnosis of well-differentiated neuroendocrine tumor with infiltration of mesenteric fat (pT3Nx). [1] [2] [3] [4] [5] [6] [7] [8]
