Metastatic Neuroendocrine Tumor of the Digestive Tract in the Liver

Neuroendocrine tumors of the digestive tract (NETDT) are a subgroup of neuroendocrine tumors (NET) that develop from neuroendocrine cells located in the digestive tract wall. This article presents the case of a 42-year-old patient diagnosed with a metastatic small bowel neuroendocrine tumor in the liver. The anatomopathological examination revealed a morphological and immunohistochemical profile consistent with a well-differentiated grade 2 digestive-origin neuroendocrine tumor with hepatic localization. A multidisciplinary tumor board reviewed the patient’s case and recommended resection of the mass with cholecystectomy to prevent complications from planned postoperative systemic therapies (gallstone disease). The patient underwent surgery, including mesenteric mass resection involving 10 cm of the small bowel with a sub-stenosing mass, termino-terminal small bowel anastomosis, and retrograde cholecystectomy
