Abstract

|
|
|
Gastric neuroendocrine tumor is an uncommon entity, and it constitutes less than 1% of all neuroendocrine tumors and less than 2% of all gastric neoplasms. Regardless of its origin, approximately 75% of the patients with neuroendocrine tumors will develop liver metastasis. We report here on two cases of primary neuroendocrine tumor with hepatic metastasis. A 37-year-old-man presented with chronic and intermittent abdominal pain in the epigastric area. He was diagnosed with gastric neuroendocrine tumor together with hepatic metastasis, based on the imaging studies and the octreotide scan. Subtotal gastrectomy and right hemihepatectomy was done and the patient was discharged on the postoperative 15th day without any complication. Another 41-year-old man presented with abdominal discomfort and a RUQ palpable mass. He was diagnosed with hepatocellular carcinoma based on the abdominal computerized tomography (CT). However, we incidentally found a gastric mass in the operating field and subtotal gastrectomy was then done. The pathologic report was large cell neuroendocrine carcinoma. The patient was discharged on the postoperative 19th day without any complication.
