ABSTRACT
Introduction: neuroendocrine tumors are rare and heterogeneous neoplasms arising from enterochromaffin cells and are the leading cause of malignancy in the small intestine. They are often diagnosed at advanced stages, with metastasis present in 30% of cases at diagnosis. Clinical case: a 70-year-old female with a history of type II diabetes mellitus and hypertension presents with recurrent gastrointestinal bleeding. Initial endoscopic studies failed to determine the source of the bleeding, leading to abdominal angiography, which revealed an intestinal tumor and surrounding mesenteric fi brosis. A laparoscopic intestinal resection was performed, yielding a histopathological result of grade 2 neuroendocrine tumor. Conclusions: surgical management is the most critical aspect of treatment, aiming for complete resection (R0). During the procedure, sequential bimanual palpation of the small intestine from the Treitz angle to the ileocecal valve is essential to rule out lesions in other sites.REFERENCES
