Introduction: Neuroendocrine tumors develop throughout gastrointestinal tract. The concurrence of mixed adenocarcinoma and neuroendocrine tumor together in the stomach is rare. Case report: We report two cases of poorly differentiated carcinoma stomach with neuroendocrine component. These patients underwent radical total gastrectomy with D2 lymph node dissection followed by adjuvant chemotherap...

Hepatoid adenocarcinomas of the stomach are gastric carcinomas with both adenocarcinomatous and hepatocellular differentiations. The tumor was characterized by high serum alpha-fetoprotein (AFP) levels. A 73-year-old male patient was admitted to the hospital with abdominal pain. Gastrofiberscopy revealed a gastric tumor occupying the antrum and pylorus. Radical subtotal gastrectomy was done and...

alpha-fetoprotein producing gastric cancer accounts for less than 10% of the gastric adenocarcinomas. different histologic subtypes may exist, the least common of which is yolk sac morphology. to the best of our knowledge less than 10 cases have been reported with high alpha-fetoprotein and yolk sac components, either pure or mixed with ordinary adenocarcinoma of the stomach. during 10 years, f...
